The distance between City Z and City A was 740 km apart. A bus travelled at an average speed of 98 km/h from City Z to City A. At the same time, a lorry travelled at an average speed of 87 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
= 98 + 87
= 185 km/h
Time taken for the bus and the lorry to meet
= 740 ÷ 185
= 4 h
Difference in the speed between the bus and the lorry
= 98 - 87
= 11 km/h
Distance that the bus travelled further than the lorry
= 4 x 11
= 44 km
Answer(s): 44 km
