Question
A train is travelling at the rate of 126 km/hr. How many
seconds it will take to cover a distance of 7/8 km?Solution
Speed of train = 126 km/hr Speed of train in (m/sec) = 126 x 5/18 = 35 m/sec Distance = 7/8 of 1 km = 7/8 x 1000 m = 875 m Therefore, Speed = distance/time 35 = 875/t Time = 875/35 = 25 sec
