A jogger jogs from one end to the other of a straight track in 1.03 min and then back to the starting point in 1.53 min. What is the jogger's average speed at the following points? (Assume the track is 100 m long.)
To find the average speed at different points, we need to divide the total distance by the total time.
Total distance covered = 2 * 100 m = 200 m (since the jogger goes from one end to the other and back)
Total time taken = 1.03 min + 1.53 min = 2.56 min
Average speed = Total distance covered / Total time taken
Therefore, the jogger's average speed at different points is:
- Starting point: (0 m) / (2.56 min) = 0 m/min
- One end: (100 m) / (2.56 min) ≈ 39.06 m/min
- Other end: (100 m) / (2.56 min) ≈ 39.06 m/min
