Question
A train covers 150 km in 100 minutes. If the speed of the train decreases by 25 km/h, find approximate how long it will take to travel the same distance.
Solution
ATQ, Speed of the train = (150/100) Γ 60 = 90 km/h New speed of the train = 90 β 25 = 65 km/h So, required time = (150/65) Γ 60 = 138.46 minutes or approximately 2 hours and 18 minutes
