Question

A truck covers a distance of 480 m in 2 minutes where as a bus covers a distance of 36 km in 3/5 hrs. The ratio of their speeds is? 
1. 2 : 25
2. 25 : 6
3. 6 : 25
4. 8 : 27

Answer 1

Correct Answer - Option 3 : 6 : 25

Given:

Truck travels 480 m in 2 min

Bus travels 36 km in 3/5 hrs

Formula used:

Speed = distance/time

Calculation:

Truck's speed = 480/120 = 4 m/s

3/5 hrs = 36 min

Bus' speed = 36000/36 × 60 = 50/3 m/s

Required ratio = 4 : 50/3 = 6 : 25

∴ the ratio is 6 : 25
