The distance between City D and City E was 830 km apart. A van travelled at an average speed of 86 km/h from City D to City E. At the same time, a convertible travelled at an average speed of 80 km/h from City E to City D. 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
= 86 + 80
= 166 km/h
Time taken for the van and the convertible to meet
= 830 ÷ 166
= 5 h
Difference in the speed between the van and the convertible
= 86 - 80
= 6 km/h
Distance that the van travelled further than the convertible
= 5 x 6
= 30 km
Answer(s): 30 km
