The distance between City Z and City A was 850 km apart. A bus travelled at an average speed of 89 km/h from City Z to City A. At the same time, a van travelled at an average speed of 81 km/h from City A to City Z. 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
= 89 + 81
= 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
= 89 - 81
= 8 km/h
Distance that the bus travelled further than the van
= 5 x 8
= 40 km
Answer(s): 40 km
