If a bus travels 160 km in 4 hours and a train travels 320 km in 5 hours

• Time Distance

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 distances travelled by them in one hour?

1. 4 : 5
2. 1 : 2
3. 8 : 5
4. 5 : 8

Answer

Bus travels 160 km in 4 hours

Speed of bus = 160/4 = 40 km/hr

Train travels 320 km in 5 hours

Speed of train = 320/5 = 64 km/hr

In one hour, bus travels 40 km and train travels 64 km.

Ratio = 40:64 = 5:8

The correct option is D.
