The distance between City S and City T was 790 km apart. A sports car travelled at an average speed of 82 km/h from City S to City T. At the same time, a car travelled at an average speed of 76 km/h from City T to City S. How much further did the sports car travel than the car when the sports car met the car on the way?
Combined speed of the sports car and the car
= 82 + 76
= 158 km/h
Time taken for the sports car and the car to meet
= 790 ÷ 158
= 5 h
Difference in the speed between the sports car and the car
= 82 - 76
= 6 km/h
Distance that the sports car travelled further than the car
= 5 x 6
= 30 km
Answer(s): 30 km
