The distance between City L and City M was 960 km apart. A van travelled at an average speed of 81 km/h from City L to City M. At the same time, a bus travelled at an average speed of 79 km/h from City M to City L. 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
= 81 + 79
= 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
= 81 - 79
= 2 km/h
Distance that the van travelled further than the bus
= 6 x 2
= 12 km
Answer(s): 12 km
