The distance between City V and City W was 620 km apart. A van travelled at an average speed of 80 km/h from City V to City W. At the same time, a convertible travelled at an average speed of 75 km/h from City W to City V. 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
= 80 + 75
= 155 km/h
Time taken for the van and the convertible to meet
= 620 ÷ 155
= 4 h
Difference in the speed between the van and the convertible
= 80 - 75
= 5 km/h
Distance that the van travelled further than the convertible
= 4 x 5
= 20 km
Answer(s): 20 km
