Question
A train is travelling at the rate of 54 km/hr. How many
seconds it will take to cover a distance of 3/5 km?Solution
Speed of train = 54 km/hr Speed of train in (m/sec) = 54 x 5/18 = 15 m/sec Distance = 3/5 of 1 km = 3/5 x 1000 m = 600 m Therefore, Speed = distance/time 15 = 600/t Time = 600/15 = 40 sec
