The distance between City U and City V was 850 km apart. A bus travelled at an average speed of 97 km/h from City U to City V. At the same time, a van travelled at an average speed of 73 km/h from City V to City U. 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
= 97 + 73
= 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
= 97 - 73
= 24 km/h
Distance that the bus travelled further than the van
= 5 x 24
= 120 km
Answer(s): 120 km
