Question
The speed of a scooter is 80 km/h and it takes 5 hours
to cover a certain distance. A car covers the same distance in 4 hours. If the speed of the scooter is increased by 30% and the speed of the car is decreased by 10%, then find the difference between the new speeds of the scooter and car.Solution
ATQ, Distance covered by the scooter = 80 × 5 = 400 km Speed of the car = 400 / 4 = 100 km/h Increased speed of the scooter = 80 × 1.3 = 104 km/h Decreased speed of the car = 100 × 0.9 = 90 km/h Required difference = 104 - 90 = 14 km/hr
