The distance between City D and City E was 700 km apart. A convertible travelled at an average speed of 88 km/h from City D to City E. At the same time, a van travelled at an average speed of 87 km/h from City E to City D. How much further did the convertible travel than the van when the convertible met the van on the way?
Combined speed of the convertible and the van
= 88 + 87
= 175 km/h
Time taken for the convertible and the van to meet
= 700 ÷ 175
= 4 h
Difference in the speed between the convertible and the van
= 88 - 87
= 1 km/h
Distance that the convertible travelled further than the van
= 4 x 1
= 4 km
Answer(s): 4 km
