Question

If a bus travels 160 km in 4 hours and a train travels 320 km in 5 hours at uniform speeds, then what is the ratio of the distance travelled by them in one hour
1. 8 ∶ 5
2. 5 ∶ 8
3. 4 ∶ 5
4. 1 ∶ 2

Answer 1

Correct Answer - Option 2 : 5 ∶ 8

Given:

Distance travels by a bus in 4 hrs = 160 km

Distance travels by a train in 5 hrs = 320 km

Formula used:

Distance = Speed × Time

Calculation:

Speed of a bus = 160/4 km/hr

⇒ 40 km/hr

Speed of a train = 320/5 km/hr

⇒ 64 km/hr

Required ratio = (40 : 64) 

⇒ 5 : 8

∴ The ratio of the distance travelled by them in one hour is 5 : 8
