The distance between City K and City L was 960 km apart. A van travelled at an average speed of 90 km/h from City K to City L. At the same time, a bus travelled at an average speed of 70 km/h from City L to City K. How much further did the van travel than the bus when the van met the bus on the way?
Combined speed of the van and the bus
= 90 + 70
= 160 km/h
Time taken for the van and the bus to meet
= 960 ÷ 160
= 6 h
Difference in the speed between the van and the bus
= 90 - 70
= 20 km/h
Distance that the van travelled further than the bus
= 6 x 20
= 120 km
Answer(s): 120 km
