The distance between City S and City T was 700 km apart. A sports car travelled at an average speed of 91 km/h from City S to City T. At the same time, a convertible travelled at an average speed of 84 km/h from City T to City S. How much further did the sports car travel than the convertible when the sports car met the convertible on the way?
Combined speed of the sports car and the convertible
= 91 + 84
= 175 km/h
Time taken for the sports car and the convertible to meet
= 700 ÷ 175
= 4 h
Difference in the speed between the sports car and the convertible
= 91 - 84
= 7 km/h
Distance that the sports car travelled further than the convertible
= 4 x 7
= 28 km
Answer(s): 28 km
