How do i find the average speed for his question: "a bicycle racer rides from a starting marker at 10m/s. she then rides back along the same rout from the turnaround marker at 16m/s. what is her average speed for the whole race? ",

To find the average speed for the whole race, you just have to add the speed from a starting marker and the speed from the turnaround marker going back and divide it by 2 since there are only two speeds involved.

10 m/s + 16m/s = 26 m/s / 2 = 13 m/s

Therefore, the average speed for the whole race is 13 m/s.
