Question

A car covers a distance of 500 meters in 20 seconds and a bus covers a distance of 30 km in 45 minutes. What is the ratio of their speed?
1. 6 : 9
2. 9 : 4
3. 4 : 9
4. 9 : 6

Answer 1

Correct Answer - Option 2 : 9 : 4

Given:

Car cover distance 500 meters in 20 seconds

Bus cover distance 30 km in 45 minutes

Calculation:

⇒ Speed of Car = 500/20 = 25 m/s = 25 × (18/5) kmph = 90 kmph

⇒ Speed of Bus = 30/(45/60) = 40 kmph

⇒ Ratio of there speed = 90/40 = 9 : 4

∴ The required result will be 9 : 4.
