The distance between City L and City M was 640 km apart. A car travelled at an average speed of 87 km/h from City L to City M. At the same time, a van travelled at an average speed of 73 km/h from City M to City L. How much further did the car travel than the van when the car met the van on the way?
Combined speed of the car and the van
= 87 + 73
= 160 km/h
Time taken for the car and the van to meet
= 640 ÷ 160
= 4 h
Difference in the speed between the car and the van
= 87 - 73
= 14 km/h
Distance that the car travelled further than the van
= 4 x 14
= 56 km
Answer(s): 56 km
