The distance between City V and City W was 910 km apart. A van travelled at an average speed of 99 km/h from City V to City W. At the same time, a lorry travelled at an average speed of 83 km/h from City W to City V. 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
= 99 + 83
= 182 km/h
Time taken for the van and the lorry to meet
= 910 ÷ 182
= 5 h
Difference in the speed between the van and the lorry
= 99 - 83
= 16 km/h
Distance that the van travelled further than the lorry
= 5 x 16
= 80 km
Answer(s): 80 km
