The distance between City L and City M was 850 km apart. A bus travelled at an average speed of 86 km/h from City L to City M. At the same time, a van travelled at an average speed of 84 km/h from City M to City L. How much further did the bus travel than the van when the bus met the van on the way?
Combined speed of the bus and the van
= 86 + 84
= 170 km/h
Time taken for the bus and the van to meet
= 850 ÷ 170
= 5 h
Difference in the speed between the bus and the van
= 86 - 84
= 2 km/h
Distance that the bus travelled further than the van
= 5 x 2
= 10 km
Answer(s): 10 km
