The distance between City M and City N was 990 km apart. A van travelled at an average speed of 91 km/h from City M to City N. At the same time, a car travelled at an average speed of 74 km/h from City N to City M. 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
= 91 + 74
= 165 km/h
Time taken for the van and the car to meet
= 990 ÷ 165
= 6 h
Difference in the speed between the van and the car
= 91 - 74
= 17 km/h
Distance that the van travelled further than the car
= 6 x 17
= 102 km
Answer(s): 102 km
