The distance between City B and City C was 790 km apart. A van travelled at an average speed of 85 km/h from City B to City C. At the same time, a car travelled at an average speed of 73 km/h from City C to City B. How much further did the van travel than the car when the van met the car on the way?
Combined speed of the van and the car
= 85 + 73
= 158 km/h
Time taken for the van and the car to meet
= 790 ÷ 158
= 5 h
Difference in the speed between the van and the car
= 85 - 73
= 12 km/h
Distance that the van travelled further than the car
= 5 x 12
= 60 km
Answer(s): 60 km
