The distance between City K and City L was 870 km apart. A convertible travelled at an average speed of 96 km/h from City K to City L. At the same time, a van travelled at an average speed of 78 km/h from City L to City K. 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
= 96 + 78
= 174 km/h
Time taken for the convertible and the van to meet
= 870 ÷ 174
= 5 h
Difference in the speed between the convertible and the van
= 96 - 78
= 18 km/h
Distance that the convertible travelled further than the van
= 5 x 18
= 90 km
Answer(s): 90 km
