The distance between City L and City M was 720 km apart. A convertible travelled at an average speed of 91 km/h from City L to City M. At the same time, a van travelled at an average speed of 89 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
= 91 + 89
= 180 km/h
Time taken for the convertible and the van to meet
= 720 ÷ 180
= 4 h
Difference in the speed between the convertible and the van
= 91 - 89
= 2 km/h
Distance that the convertible travelled further than the van
= 4 x 2
= 8 km
Answer(s): 8 km
