The distance between City D and City E was 720 km apart. A bus travelled at an average speed of 98 km/h from City D to City E. At the same time, a van travelled at an average speed of 82 km/h from City E to City D. 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
= 98 + 82
= 180 km/h
Time taken for the bus and the van to meet
= 720 ÷ 180
= 4 h
Difference in the speed between the bus and the van
= 98 - 82
= 16 km/h
Distance that the bus travelled further than the van
= 4 x 16
= 64 km
Answer(s): 64 km
