Question

A bus covers 128 km in 2 hours and a train covers 240 km in 3 hours. Find the ratio of their speeds.

Answer 1

A bus covers 128 km in 2 hours.
Speed of the bus = Distance = 128 km = 64 km/ hr
Time 2 hr

A train covers 240 km in 3 hours.
Speed of the train = Distance = 240 = 80 km /hr
Time 3

Ratio of their speeds = 64:80 = 64 = 64 ÷ 16 = 4
80 80 ÷ 16 5
$\therefore$ Ratio of the speeds of the bus and the train = 4:5
