The distance between City C and City D was 890 km apart. A convertible travelled at an average speed of 97 km/h from City C to City D. At the same time, a car travelled at an average speed of 81 km/h from City D to City C. 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
= 97 + 81
= 178 km/h
Time taken for the convertible and the car to meet
= 890 ÷ 178
= 5 h
Difference in the speed between the convertible and the car
= 97 - 81
= 16 km/h
Distance that the convertible travelled further than the car
= 5 x 16
= 80 km
Answer(s): 80 km
