The distance between City G and City H was 840 km apart. A bus travelled at an average speed of 96 km/h from City G to City H. At the same time, a van travelled at an average speed of 72 km/h from City H to City G. 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
= 96 + 72
= 168 km/h
Time taken for the bus and the van to meet
= 840 ÷ 168
= 5 h
Difference in the speed between the bus and the van
= 96 - 72
= 24 km/h
Distance that the bus travelled further than the van
= 5 x 24
= 120 km
Answer(s): 120 km
