Solved Example
Step-by-step example
Practice example: A car covers 240 km in 4 hours and then 180 km in 3 hours. What is its average speed for the complete journey?
Solution: The average speed is 60 km/h.
Practice Preview
Before you solve
- A bus covers the first 120 km at 40 km/h and the next 180 km at 60 km/h. What is the average speed for the whole journey?
- A car travels 150 km at 50 km/h and 210 km at 70 km/h. What is the average speed for the whole journey?

Learn the shortcut first
Shortcut before you solve
Most speed questions are easy once the units are made uniform first.
Featured shortcut
Use S = D / T and convert units before solving.
Exam-use rule
Speed = Distance / Time, Distance = Speed x Time, Time = Distance / Speed.
Use this in 3 seconds
First check the units, then apply the basic formula.
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.

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.
Real exam shortcut before you solve
A car covers 120 km in 2 hours. Find its speed.
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
Worked example
A car covers 120 km in 2 hours. Find its speed.
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.
