The distance between City D and City E was 840 km apart. A car travelled at an average speed of 94 km/h from City D to City E. At the same time, a convertible travelled at an average speed of 74 km/h from City E to City D. 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
= 94 + 74
= 168 km/h
Time taken for the car and the convertible to meet
= 840 ÷ 168
= 5 h
Difference in the speed between the car and the convertible
= 94 - 74
= 20 km/h
Distance that the car travelled further than the convertible
= 5 x 20
= 100 km
Answer(s): 100 km
