The distance between City Z and City A was 700 km apart. A lorry travelled at an average speed of 93 km/h from City Z to City A. At the same time, a bus travelled at an average speed of 82 km/h from City A to City Z. How much further did the lorry travel than the bus when the lorry met the bus on the way?
Combined speed of the lorry and the bus
= 93 + 82
= 175 km/h
Time taken for the lorry and the bus to meet
= 700 ÷ 175
= 4 h
Difference in the speed between the lorry and the bus
= 93 - 82
= 11 km/h
Distance that the lorry travelled further than the bus
= 4 x 11
= 44 km
Answer(s): 44 km
