The distance between City U and City V was 960 km apart. A van travelled at an average speed of 89 km/h from City U to City V. At the same time, a lorry travelled at an average speed of 71 km/h from City V to City U. How much further did the van travel than the lorry when the van met the lorry on the way?
Combined speed of the van and the lorry
= 89 + 71
= 160 km/h
Time taken for the van and the lorry to meet
= 960 ÷ 160
= 6 h
Difference in the speed between the van and the lorry
= 89 - 71
= 18 km/h
Distance that the van travelled further than the lorry
= 6 x 18
= 108 km
Answer(s): 108 km
