The distance between City E and City F was 900 km apart. A van travelled at an average speed of 98 km/h from City E to City F. At the same time, a lorry travelled at an average speed of 82 km/h from City F to City E. 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
= 98 + 82
= 180 km/h
Time taken for the van and the lorry to meet
= 900 ÷ 180
= 5 h
Difference in the speed between the van and the lorry
= 98 - 82
= 16 km/h
Distance that the van travelled further than the lorry
= 5 x 16
= 80 km
Answer(s): 80 km
