The distance between City W and City X was 770 km apart. A van travelled at an average speed of 81 km/h from City W to City X. At the same time, a convertible travelled at an average speed of 73 km/h from City X to City W. How much further did the van travel than the convertible when the van met the convertible on the way?
Combined speed of the van and the convertible
= 81 + 73
= 154 km/h
Time taken for the van and the convertible to meet
= 770 ÷ 154
= 5 h
Difference in the speed between the van and the convertible
= 81 - 73
= 8 km/h
Distance that the van travelled further than the convertible
= 5 x 8
= 40 km
Answer(s): 40 km
