A car travels at a speed of 90 km/h and takes 4.5 hours
to cover a specific distance. A train can cover the same distance in 3 hours. If the speed of the car is increased by 40% and the speed of the train is decreased by 20%, determine the difference between the new speeds of the car and the train.Solution
ATQ, Distance covered by car = 90 × 4.5 = 405 km Speed of the train = 405/3 = 135 km/h Increased speed of the car = 90 × 1.4 = 126 km/h Decreased speed of the train = 135 × 0.8 = 108 km/h Required difference = 126 – 108 = 18 km/hr
