If a bus travels 160 km in 4 hours and a train travels 320km in 5 hours at uniform speeds, then the ratio of the distances travelled by them in one hour is


As speed =


Speed of bus = 40km/hr


Speed of train = 64km/hr


Distance travelled in 1 hr by bus = 40km


Distance travelled in 1 hr by train = 64km


Ratio of distance travelled by bus to train =
