The distance between City C and City D was 960 km apart. A van travelled at an average speed of 87 km/h from City C to City D. At the same time, a convertible travelled at an average speed of 73 km/h from City D to City C. 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
= 87 + 73
= 160 km/h
Time taken for the van and the convertible to meet
= 960 ÷ 160
= 6 h
Difference in the speed between the van and the convertible
= 87 - 73
= 14 km/h
Distance that the van travelled further than the convertible
= 6 x 14
= 84 km
Answer(s): 84 km
