The distance between City U and City V was 840 km apart. A lorry travelled at an average speed of 95 km/h from City U to City V. At the same time, a van travelled at an average speed of 73 km/h from City V to City U. How much further did the lorry travel than the van when the lorry met the van on the way?
Combined speed of the lorry and the van
= 95 + 73
= 168 km/h
Time taken for the lorry and the van to meet
= 840 ÷ 168
= 5 h
Difference in the speed between the lorry and the van
= 95 - 73
= 22 km/h
Distance that the lorry travelled further than the van
= 5 x 22
= 110 km
Answer(s): 110 km
