The distance between City B and City C was 930 km apart. A car travelled at an average speed of 85 km/h from City B to City C. At the same time, a van travelled at an average speed of 70 km/h from City C to City B. How much further did the car travel than the van when the car met the van on the way?
Combined speed of the car and the van
= 85 + 70
= 155 km/h
Time taken for the car and the van to meet
= 930 ÷ 155
= 6 h
Difference in the speed between the car and the van
= 85 - 70
= 15 km/h
Distance that the car travelled further than the van
= 6 x 15
= 90 km
Answer(s): 90 km
