The distance between City U and City V was 810 km apart. A van travelled at an average speed of 85 km/h from City U to City V. At the same time, a convertible travelled at an average speed of 77 km/h from City V to City U. 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
= 85 + 77
= 162 km/h
Time taken for the van and the convertible to meet
= 810 ÷ 162
= 5 h
Difference in the speed between the van and the convertible
= 85 - 77
= 8 km/h
Distance that the van travelled further than the convertible
= 5 x 8
= 40 km
Answer(s): 40 km
