The distance between City W and City X was 990 km apart. A bus travelled at an average speed of 88 km/h from City W to City X. At the same time, a van travelled at an average speed of 77 km/h from City X to City W. 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
= 88 + 77
= 165 km/h
Time taken for the bus and the van to meet
= 990 ÷ 165
= 6 h
Difference in the speed between the bus and the van
= 88 - 77
= 11 km/h
Distance that the bus travelled further than the van
= 6 x 11
= 66 km
Answer(s): 66 km
