Summary Formula Tricks Mistakes Solved Example Practice FAQ

Time Speed Distance revision for SSC CHSL: understand the base rule, apply the correct formula or relation, check common traps, then practise with approved questions.

Time, Speed and Distance are linked by distance = speed × time. The most common errors come from inconsistent units or comparing average speeds incorrectly.

SSC CHSL focus: Solve the core method first, then use the approved practice questions on this page to build exam-speed accuracy.

Time Speed Distance revision rule: concept → formula/relation → one worked example → timed practice → error review.

Core concept
Key formula/relation

Approved practice

D = ST
S = D/T
T = D/S
km/h to m/s: ×5/18; m/s to km/h: ×18/5

For equal distances at speeds a and b, average speed = 2ab/(a+b).

Using a memorised shortcut without checking its condition.
Skipping unit or base conversion.
Doing long arithmetic before identifying the underlying relation.

Practice example: A train moves at 54 km/h. How much distance will it cover in 30 seconds?

Solution: The train covers 450 m.

A car covers 150 km at a constant speed of 50 km/h. How much time does it take?
A vehicle travels at 72 km/h. How far does it travel in 25 seconds?
In a Time Speed Distance practice set, a student answers 18 questions correctly out of 24. What percentage is correct?

Learn the shortcut first

Shortcut before you solve

Most speed questions are easy once the units are made uniform first.

Faster solving steps

Use this 4-step method before solving to keep your thinking fast and repeatable.

Step 1 Identify relation

Spot the pattern, relationship, or core idea first.

Step 2 Apply same pattern

Use the same rule instead of re-solving from scratch.

Step 3 Eliminate wrong options

Remove confusing choices before comparing the last few.

Step 4 Confirm final answer

Pick the option that matches the shortcut most cleanly.

Now apply the trick on real questions

Use the shortcut above before solving these questions

Use S = D / T and convert units before solving.

Tip: To change km/h into m/s, multiply by 5/18. To change m/s into km/h, multiply by 18/5.

Step 1

Speed = Distance / Time.

Step 2

120 / 2 = 60 km/h.

Rule

Speed = Distance / Time, Distance = Speed x Time, Time = Distance / Speed.

3-second trick

First check the units, then apply the basic formula.

Trap to avoid

Do not mix metres and kilometres or seconds and hours in one formula.

Correct answer

60 km/h

Thinking path

Distance is 120 km.
Time is 2 hours.
So speed is 60 km/h.

Final answer: 60 km/h

Why this is fast: The direct formula works instantly when units are consistent.
