The distance between City H and City J was 740 km apart. A convertible travelled at an average speed of 96 km/h from City H to City J. At the same time, a lorry travelled at an average speed of 89 km/h from City J to City H. How much further did the convertible travel than the lorry when the convertible met the lorry on the way?
Combined speed of the convertible and the lorry
= 96 + 89
= 185 km/h
Time taken for the convertible and the lorry to meet
= 740 ÷ 185
= 4 h
Difference in the speed between the convertible and the lorry
= 96 - 89
= 7 km/h
Distance that the convertible travelled further than the lorry
= 4 x 7
= 28 km
Answer(s): 28 km
