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 the speed of bus.
Solution
Distance travelled by bus = 180 km
Time taken = 3 hours
Speed = `"Distance"/" Time"=180/3` = 60 km/hr
Distance travelled by train = 450 km
Time taken = 5 hours
Speed =`"Distance"/" Time"=450/5`= 90 km/hr
Ratio of speed of the train to the speed of bus = 90 : 60 = 3 : 2
