Question
A train takes 16 seconds to pass a pole and 36 seconds
to cross a platform 250 meters long. Calculate the total distance the train would cover if it traveled continuously for 5 hours.Solution
Let speed of train is ‘x’ m/s and length of train is ‘l’ metres According to question; l = 16x And, l + 250 = 36x Or, 16x + 250 = 36x Or, 20x = 250 Or, x = 12.5 Speed of train = 12.5 × 18/5 = 45 km/h Distance travelled by train in 5 hours = 45 × 5 = 225 km Hence, option a.
