The distance between City V and City W was 910 km apart. A lorry travelled at an average speed of 95 km/h from City V to City W. At the same time, a convertible travelled at an average speed of 87 km/h from City W to City V. How much further did the lorry travel than the convertible when the lorry met the convertible on the way?
Combined speed of the lorry and the convertible
= 95 + 87
= 182 km/h
Time taken for the lorry and the convertible to meet
= 910 ÷ 182
= 5 h
Difference in the speed between the lorry and the convertible
= 95 - 87
= 8 km/h
Distance that the lorry travelled further than the convertible
= 5 x 8
= 40 km
Answer(s): 40 km
