The distance between City N and City P was 800 km apart. A sports car travelled at an average speed of 90 km/h from City N to City P. At the same time, a van travelled at an average speed of 70 km/h from City P to City N. How much further did the sports car travel than the van when the sports car met the van on the way?
Combined speed of the sports car and the van
= 90 + 70
= 160 km/h
Time taken for the sports car and the van to meet
= 800 ÷ 160
= 5 h
Difference in the speed between the sports car and the van
= 90 - 70
= 20 km/h
Distance that the sports car travelled further than the van
= 5 x 20
= 100 km
Answer(s): 100 km
