Question

A bus travels 180 km in 3 hours and a train travels 450 km in 5 hours. Find the ratio of speed of train to speed of bus.

Answer 1

Distance travelled by bus = 180 km

Time taken = 3 hours

Speed = \frac { Distance }{ Time } =\frac { 180 }{ 3 } = 60 km/hr

Distance travelled by train = 450 km

Time taken = 5 hours

Speed = \frac { Distance }{ Time } =\frac { 450 }{ 5 } = 90 km/hr

Ratio of speed of train to speed of bus = 90 : 60 = 3 : 2
