The distance between City V and City W was 620 km apart. A convertible travelled at an average speed of 83 km/h from City V to City W. At the same time, a van travelled at an average speed of 72 km/h from City W to City V. How much further did the convertible travel than the van when the convertible met the van on the way?
Combined speed of the convertible and the van
= 83 + 72
= 155 km/h
Time taken for the convertible and the van to meet
= 620 ÷ 155
= 4 h
Difference in the speed between the convertible and the van
= 83 - 72
= 11 km/h
Distance that the convertible travelled further than the van
= 4 x 11
= 44 km
Answer(s): 44 km
