Question

a bus covers 128 km in 2 hour and a train covered 240 km in 3 hour find the ratio of their speed

Answer 1

Solution:-

Speed of the bus = 128/2

Speed of the bus = 64 km per hour

Speed of the train = 240/3

Speed of the train = 80 km per hour

Ratio of their speed

64 : 80

4 : 5

Answer 2

Distance covered by bus=128 km
Time taken by bus to cover the distance=2 hours
Speed of bus=Distance/Time
=128/2
=64Kmph
Distance covered by train=240km
Time taken by train to cover the distance=3 hours
Speed of train =Distance/Time
=240/3
=80 Kmph
Ratio of speed of bus to train=64:80=8:10=4:5
