The distance between City E and City F was 830 km apart. A bus travelled at an average speed of 89 km/h from City E to City F. At the same time, a van travelled at an average speed of 77 km/h from City F to City E. 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 + 77
= 166 km/h
Time taken for the bus and the van to meet
= 830 ÷ 166
= 5 h
Difference in the speed between the bus and the van
= 89 - 77
= 12 km/h
Distance that the bus travelled further than the van
= 5 x 12
= 60 km
Answer(s): 60 km
