Question
A train covers 150 km in 100 minutes. If its speed is
reduced by 30 km/h, how much time will it take to travel the same distance?Solution
ATQ,
Speed of the train = (150 / 100) × 60 = 90 km/h
New speed of the train = 90 - 30 = 60 km/h
So, required time = (150 / 60) × 60 = 150 minutes or 2 hours and 30 minutes
