Question
Point A and Point B are 60 m apart. Point B and Point C are 150 m apart. Ben ran from Point A to Point B in 3 seconds.
Then, he runs from Point B to Point C in 11 seconds. Find Ben’s average speed for the distance from Point A to Point C.
- 10m/s
- 15m/s
- 20m/s
- 25 m/s
The correct answer is: 15m/s
Average speed = total distance travelled
Total time taken
Total distance from point A to C = 60 + 150 =210m
Time taken to run from point A to point C = 11 + 3 = 14s
Average speed = 210/14 = 30/2=15/1 = 15m/s
