The distance between City R and City S was 750 km apart. A convertible travelled at an average speed of 80 km/h from City R to City S. At the same time, a car travelled at an average speed of 70 km/h from City S to City R. How much further did the convertible travel than the car when the convertible met the car on the way?
Combined speed of the convertible and the car
= 80 + 70
= 150 km/h
Time taken for the convertible and the car to meet
= 750 ÷ 150
= 5 h
Difference in the speed between the convertible and the car
= 80 - 70
= 10 km/h
Distance that the convertible travelled further than the car
= 5 x 10
= 50 km
Answer(s): 50 km
