The distance between City W and City X was 930 km apart. A lorry travelled at an average speed of 98 km/h from City W to City X. At the same time, a convertible travelled at an average speed of 88 km/h from City X to City W. 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
= 98 + 88
= 186 km/h
Time taken for the lorry and the convertible to meet
= 930 ÷ 186
= 5 h
Difference in the speed between the lorry and the convertible
= 98 - 88
= 10 km/h
Distance that the lorry travelled further than the convertible
= 5 x 10
= 50 km
Answer(s): 50 km
