Question

Two cars, A and B, are travelling along a straight road and in the same direction. Car B is 20 km

ahead of Car A. Car A is travelling at 60 km · while Car B at 50 km 1. They both start at 12:00
hours. At what time Car A will overtake Car B?

Answer 1

2 o'clock

Explanation:

Their 'closing speed' is 60 - 50 = 10 km/hr

they have 20 km between them

at closing speed this will take 20 km / 10 km/hr = 2 hours for the cars to meet....this would be at 14:00 or 2 oclock
