The distance between City Q and City R was 720 km apart. A van travelled at an average speed of 93 km/h from City Q to City R. At the same time, a bus travelled at an average speed of 87 km/h from City R to City Q. How much further did the van travel than the bus when the van met the bus on the way?
Combined speed of the van and the bus
= 93 + 87
= 180 km/h
Time taken for the van and the bus to meet
= 720 ÷ 180
= 4 h
Difference in the speed between the van and the bus
= 93 - 87
= 6 km/h
Distance that the van travelled further than the bus
= 4 x 6
= 24 km
Answer(s): 24 km
