The distance between City M and City N was 800 km apart. A van travelled at an average speed of 83 km/h from City M to City N. At the same time, a sports car travelled at an average speed of 77 km/h from City N to City M. How much further did the van travel than the sports car when the van met the sports car on the way?
Combined speed of the van and the sports car
= 83 + 77
= 160 km/h
Time taken for the van and the sports car to meet
= 800 ÷ 160
= 5 h
Difference in the speed between the van and the sports car
= 83 - 77
= 6 km/h
Distance that the van travelled further than the sports car
= 5 x 6
= 30 km
Answer(s): 30 km
