The distance between City Q and City R was 830 km apart. A van travelled at an average speed of 87 km/h from City Q to City R. At the same time, a bus travelled at an average speed of 79 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
= 87 + 79
= 166 km/h
Time taken for the van and the bus to meet
= 830 ÷ 166
= 5 h
Difference in the speed between the van and the bus
= 87 - 79
= 8 km/h
Distance that the van travelled further than the bus
= 5 x 8
= 40 km
Answer(s): 40 km
