The distance between City W and City X was 810 km apart. A convertible travelled at an average speed of 82 km/h from City W to City X. At the same time, a van travelled at an average speed of 80 km/h from City X to City W. 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
= 82 + 80
= 162 km/h
Time taken for the convertible and the van to meet
= 810 ÷ 162
= 5 h
Difference in the speed between the convertible and the van
= 82 - 80
= 2 km/h
Distance that the convertible travelled further than the van
= 5 x 2
= 10 km
Answer(s): 10 km
