Question

A truck covers a distance of 550 meters in 1 minute, whereas a bus covers a distance of 33 km in 45 minute. The ratio of their speed is:
1. 3 ∶ 4
2. 2 ∶ 1
3. 2 ∶ 7
4. 3 ∶ 5

Answer 1

Correct Answer - Option 1 : 3 ∶ 4

Given:

Distance covered by truck = 550 m

Time taken by truck to cover the distance = 1 min

Distance covered by bus = 33 km = 33,000 m

Time taken by bus to cover the distance = 45 min

Concept used:

Speed = distance/time

Calculation:

Speed of truck = 550/1 = 550 m/min

Speed of bus = 33,000/45 = 2,200/3 m/min

Speed of truck ∶ Speed of bus = 550 ∶ (2,200/3) = 3 ∶ 4

∴ The ratio of the speed of the truck to the speed of the bus is 3 ∶ 4.
