The distance between City Z and City A was 870 km apart. A car travelled at an average speed of 91 km/h from City Z to City A. At the same time, a convertible travelled at an average speed of 83 km/h from City A to City Z. How much further did the car travel than the convertible when the car met the convertible on the way?
Combined speed of the car and the convertible
= 91 + 83
= 174 km/h
Time taken for the car and the convertible to meet
= 870 ÷ 174
= 5 h
Difference in the speed between the car and the convertible
= 91 - 83
= 8 km/h
Distance that the car travelled further than the convertible
= 5 x 8
= 40 km
Answer(s): 40 km
