Question
A truck moving at 30 km/h is overtaken by a train in 20
seconds. If the train is travelling at twice the speed of the truck, calculate its length.Solution
ATQ,
Speed of the truck = 30 × (5/18) = 8.33 m/s
So, speed of the train = 8.33 × 2 = 16.66 m/s
Let the length of the train be 'x' metres
ATQ:
x / (16.66 - 8.33) = 20
So, x = 166.6
Length of the train ≈ 166.6 metres
