Question
A bike travels 96 km in 72 minutes. If the speed is
reduced by 12 km/h, find the time taken to cover the same distance.Solution
ATQ, Speed of the bike = (96/72) × 60 = 80 km/h New speed of the bike = 80 – 12 = 68 km/h So, required time = (96/68) × 60 = 84.7 minutes or about 1 hour and 25 minutes
