The distance between City W and City X was 810 km apart. A van travelled at an average speed of 89 km/h from City W to City X. At the same time, a car travelled at an average speed of 73 km/h from City X to City W. 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
= 89 + 73
= 162 km/h
Time taken for the van and the car to meet
= 810 ÷ 162
= 5 h
Difference in the speed between the van and the car
= 89 - 73
= 16 km/h
Distance that the van travelled further than the car
= 5 x 16
= 80 km
Answer(s): 80 km
