The distance between City T and City U was 890 km apart. A van travelled at an average speed of 92 km/h from City T to City U. At the same time, a lorry travelled at an average speed of 86 km/h from City U to City T. 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
= 92 + 86
= 178 km/h
Time taken for the van and the lorry to meet
= 890 ÷ 178
= 5 h
Difference in the speed between the van and the lorry
= 92 - 86
= 6 km/h
Distance that the van travelled further than the lorry
= 5 x 6
= 30 km
Answer(s): 30 km
