To calculate speed the formula is D/T=S

You can substitute Distance for position since it's labeling the position it's reached from its initial start.

To find average you take all your values, add them up, and divide by how many values there are.

1.2/0.024=50

2.8/0.051=54.9 (we'll round it up to 55)

4.2/0.084=50

16.34/2.34= 6.98 (we'll round it to a 7)

50+55+50+7=162

162/4=40.5

So her average speed was 40.5 Km/h.
