The distance between City Y and City Z was 860 km apart. A van travelled at an average speed of 97 km/h from City Y to City Z. At the same time, a car travelled at an average speed of 75 km/h from City Z to City Y. 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
= 97 + 75
= 172 km/h
Time taken for the van and the car to meet
= 860 ÷ 172
= 5 h
Difference in the speed between the van and the car
= 97 - 75
= 22 km/h
Distance that the van travelled further than the car
= 5 x 22
= 110 km
Answer(s): 110 km
