Time, Speed and Distance (TSD) is an important topic of Arithmetic in CAT Quantitative Ability (QA) section. CAT 2026 QA section has 22 questions to be solved in 40 minutes. It tests the ability to interpret motion-based problems and apply the correct relationship and solve them in limited time. Common question types include relative speed, average speed, trains, boats and streams, races, and circular tracks.
For CAT 2026, concentrate on the relationship between speed, distance and time rather than just mugging up formulas. A clear understanding of these concepts also helps in other MBA entrance examinations.
Time, Speed and Distance Weightage in CAT
Time, Speed and Distance does not have a fixed, officially prescribed number of questions in CAT. Its weightage varies across years and exam slots. Questions may test TSD directly or combine it with other arithmetic concepts.
The topic appeared in CAT 2025, with exam analyses reporting TSD questions in the Quantitative Aptitude section. CAT 2024 also included a TSD question involving a train travelling at a uniform speed. These examples indicate that the topic deserves a place in your preparation plan, but they do not establish a guaranteed annual question count. Time, Speed and Distance topic is included in the Arithmetic chapter, which carries the highest weightage in recent CAT papers.

Time, Speed and Distance in CAT: Previous Year Question Analysis
CAT questions on Time, Speed, and Distance often require you to translate a verbal problem into equations. Some questions are formula-based, while others require multiple steps or a combination of concepts.
Important TSD concepts for CAT
- Basic speed, distance and time: Use the relationship between distance travelled, speed and time taken.
- Average speed: Calculate average speed using total distance divided by total time, not by automatically taking the arithmetic mean of speeds.
- Relative speed: Add speeds when two objects move towards each other and subtract them when they move in the same direction.
- Trains: Account for the lengths of trains, platforms or other objects while calculating crossing times.
- Boats and streams: Distinguish between upstream and downstream speeds.
- Races and circular tracks: Compare speeds, finishing positions, meeting times and the number of rounds completed.
CAT Previous Year Question: Train Speed
A train travelled a certain distance at a uniform speed. Had the speed been 6 km per hour more, it would have taken 4 hours less. Had the speed been 6 km per hour less, it would have taken 6 hours more. What was the distance travelled by the train?
Options: 640 km, 720 km, 780 km, 800 km.
Solution:
Let the original speed be vvv km/h and the original travel time be ttt hours.
The distance remains the same in all three cases.
vt=(v+6)(t−4)vt = (v+6)(t-4)vt=(v+6)(t−4)
Expanding and simplifying:
2v=3t−122v = 3t - 122v=3t−12
When the speed decreases by 6 km/h and the travel time increases by 6 hours:
vt=(v−6)(t+6)vt = (v-6)(t+6)vt=(v−6)(t+6)
Expanding and simplifying:
v=t+6v = t + 6v=t+6
Substituting v=t+6v = t + 6v=t+6 into the first equation:
2(t+6)=3t−122(t+6) = 3t - 122(t+6)=3t−12
t=24,v=30t = 24, \qquad v = 30t=24,v=30
Therefore,
Distance=30×24=720 km\text{Distance} = 30 \times 24 = 720 \text{ km}Distance=30×24=720 km
Correct answer: 720 km.
A person walks to a place at 4 km/h and returns at 6 km/h. Find the average speed for the round trip.
Since the distances are equal:
[latex]\text{Average Speed} = \frac{2 a b}{a+b}[/latex]
[latex]\text{Average Speed} =\frac{2 \times 4 \times 6}{4+6}=4.8 \mathrm{~km} / \mathrm{h}[/latex]
Answer: 4.8 km/h, not 5 km/h.
2. Trains moving in opposite directions
Two trains of lengths 120 m and 180 m run in opposite directions at 45 km/h and 54 km/h. Find the time taken to cross each other completely.
Relative speed:
[latex](45+54) \times \frac{5}{18}=27.5 \mathrm{~m} / \mathrm{s}[/latex]
Total distance covered:
[latex]120+180=300 \mathrm{~m}[/latex]
Time taken:
[latex]\frac{300}{27.5} \approx 10.91 seconds[/latex]
Answer: Approximately 10.91 seconds.
3. Boats and streams
A boat travels 14 km upstream and returns downstream. Its speed in still water is 6 km/h, and the stream speed is 2 km/h. Find the total journey time.
Upstream speed:
[latex]6-2=4 \mathrm{~km} / \mathrm{h}[/latex]
Downstream speed:
[latex]6+2=8 \mathrm{~km} / \mathrm{h}[/latex]
Upstream time:
[latex]\frac{14}{4}=3.5 hours[/latex]
Downstream time:
[latex]\frac{14}{8}=1.75 hours[/latex]
Total time:
[latex]3.5+1.75=5.25 hours[/latex]
Answer: 5.25 hours, or 5 hours 15 minutes.
Note: CAT 2025 had boats-and-streams questions in all three slots. Earlier papers regularly used meeting-point and train-crossing cases. Many recent TSD questions have been TITA.
How to analyse TSD questions after practising
After attempting previous year questions, record the following:
- The concept tested in each question.
- Whether you identified the correct formula or relationship.
- The time taken to reach the answer.
- Any calculation errors or incorrect assumptions.
- Whether a shorter solution was possible without sacrificing accuracy.
This analysis helps you identify whether you need to revise concepts, improve calculations or practise more difficult applications.
How to Prepare for Time, Speed and Distance for CAT 2026
A focused preparation strategy can help you improve both accuracy and speed. Follow these steps while preparing for CAT 2026.
- Revise the basic formulas
Start with the relationship between speed, distance and time. The following snapshot provides the asic formula and tips to prepare for CAT Time, Speed and Distance topic.
Time, Speed and Distance: Basic Formulas
Speed = Distance ÷ Time
Distance = Speed × Time
Time = Distance ÷ Speed
Unit Conversions
. To convert km/h into m/s, multiply by 5/18.
. To convert m/s into km/h, multiply by 18/5.
Examples :
72 km/h = 72 × 5/18
= 20 m/s
10 m/s = 10 × 18/5
= 36 km/h
CAT Preparation Tip
Always convert speed units before substituting values into a formula. Ensure distance and speed use compatible units, and convert minutes into hours when speed is expressed in km/h.
- Practise one concept at a time
Do not begin with the toughest mixed questions. Build your foundation by practising basic speed and time problems first. Then move to average speed, relative speed, trains, boats and streams, races, and circular tracks.
Once you are comfortable with individual concepts, attempt questions that combine two or more of them.
- Solve CAT previous year questions
Previous year questions help you understand how familiar concepts are tested in the actual exam. Solve them topic-wise before attempting mixed Quantitative Aptitude practice sets.
Try to solve each question independently before checking its solution. If you get an answer wrong, identify the reason rather than simply memorising the correct method.
- Practise under timed conditions
After building conceptual clarity, attempt short timed sets. Track your accuracy and average solving time. Do not rush through questions at the cost of understanding the conditions given in the problem.
During mocks, prioritise questions you can solve accurately and efficiently. If a question requires lengthy calculations, consider returning to it after attempting more manageable questions.
- Maintain an error log
Maintain a record of questions you answered incorrectly, skipped or took too long to solve. Categorise each error as a conceptual gap, calculation mistake, incorrect interpretation or inefficient approach.
Revisit this log regularly and solve similar questions until you can apply the relevant concept confidently.
- Revise formulas and common question types
In the final stage of preparation, revise your formula sheet, important conversions and common problem-solving approaches. Reattempt previously incorrect questions and take mixed practice tests to check whether you can apply concepts without relying on topic labels.
