The distance between City Z and City A was 830 km apart. A bus travelled at an average speed of 95 km/h from City Z to City A. At the same time, a lorry travelled at an average speed of 71 km/h from City A to City Z. 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
= 95 + 71
= 166 km/h
Time taken for the bus and the lorry to meet
= 830 ÷ 166
= 5 h
Difference in the speed between the bus and the lorry
= 95 - 71
= 24 km/h
Distance that the bus travelled further than the lorry
= 5 x 24
= 120 km
Answer(s): 120 km
