Question
A car typically travels 20%
faster than a bike. The bike takes 4 hours to cover 300 km. If the car's speed were 8 km/h less than usual, how much time would it take to cover 328 km?Solution
ATQ, Speed of the bike = (300/4) = 75 km/hr Usual speed of the car = 1.2 × 75 = 90 km Therefore, speed with which it travelled 328 km = 90 - 8 = 82 km/hr Required time taken = (328/82) = 4 hours
