The distance between City L and City M was 860 km apart. A convertible travelled at an average speed of 90 km/h from City L to City M. At the same time, a van travelled at an average speed of 82 km/h from City M to City L. How much further did the convertible travel than the van when the convertible met the van on the way?
Combined speed of the convertible and the van
= 90 + 82
= 172 km/h
Time taken for the convertible and the van to meet
= 860 ÷ 172
= 5 h
Difference in the speed between the convertible and the van
= 90 - 82
= 8 km/h
Distance that the convertible travelled further than the van
= 5 x 8
= 40 km
Answer(s): 40 km
