The distance between City Z and City A was 930 km apart. A convertible travelled at an average speed of 99 km/h from City Z to City A. At the same time, a van travelled at an average speed of 87 km/h from City A to City Z. 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
= 99 + 87
= 186 km/h
Time taken for the convertible and the van to meet
= 930 ÷ 186
= 5 h
Difference in the speed between the convertible and the van
= 99 - 87
= 12 km/h
Distance that the convertible travelled further than the van
= 5 x 12
= 60 km
Answer(s): 60 km
