The distance between City E and City F was 700 km apart. A car travelled at an average speed of 95 km/h from City E to City F. At the same time, a lorry travelled at an average speed of 80 km/h from City F to City E. How much further did the car travel than the lorry when the car met the lorry on the way?
Combined speed of the car and the lorry
= 95 + 80
= 175 km/h
Time taken for the car and the lorry to meet
= 700 ÷ 175
= 4 h
Difference in the speed between the car and the lorry
= 95 - 80
= 15 km/h
Distance that the car travelled further than the lorry
= 4 x 15
= 60 km
Answer(s): 60 km
