The distance between City A and City B was 890 km apart. A bus travelled at an average speed of 96 km/h from City A to City B. At the same time, a lorry travelled at an average speed of 82 km/h from City B to City A. 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
= 96 + 82
= 178 km/h
Time taken for the bus and the lorry to meet
= 890 ÷ 178
= 5 h
Difference in the speed between the bus and the lorry
= 96 - 82
= 14 km/h
Distance that the bus travelled further than the lorry
= 5 x 14
= 70 km
Answer(s): 70 km
