Question
A car covers 135 km in 3 hours. The scooter is 2.5 m/s
slower than the car. Find the scooter’s distance (in metres) in 5 minutes.Solution
ATQ,
Speed of car = (135/3) = 45 km/h = 45 × (5/18) = 12.5 m/s
Speed of scooter = 12.5 − 2.5 = 10 m/s
5 minutes = 5 × 60 = 300 seconds
Required distance = 10 × 300 = 3,000 metres
