The distance between City T and City U was 660 km apart. A bus travelled at an average speed of 94 km/h from City T to City U. At the same time, a lorry travelled at an average speed of 71 km/h from City U to City T. How much further did the bus travel than the lorry when the bus met the lorry on the way?
Combined speed of the bus and the lorry
= 94 + 71
= 165 km/h
Time taken for the bus and the lorry to meet
= 660 ÷ 165
= 4 h
Difference in the speed between the bus and the lorry
= 94 - 71
= 23 km/h
Distance that the bus travelled further than the lorry
= 4 x 23
= 92 km
Answer(s): 92 km
