The distance between City D and City E was 920 km apart. A van travelled at an average speed of 100 km/h from City D to City E. At the same time, a convertible travelled at an average speed of 84 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
= 100 + 84
= 184 km/h
Time taken for the van and the convertible to meet
= 920 ÷ 184
= 5 h
Difference in the speed between the van and the convertible
= 100 - 84
= 16 km/h
Distance that the van travelled further than the convertible
= 5 x 16
= 80 km
Answer(s): 80 km
