The distance between City T and City U was 660 km apart. A van travelled at an average speed of 86 km/h from City T to City U. At the same time, a bus travelled at an average speed of 79 km/h from City U to City T. 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
= 86 + 79
= 165 km/h
Time taken for the van and the bus to meet
= 660 ÷ 165
= 4 h
Difference in the speed between the van and the bus
= 86 - 79
= 7 km/h
Distance that the van travelled further than the bus
= 4 x 7
= 28 km
Answer(s): 28 km
