Breanna · Answer 1

0.256 m/s

Explanation:

Speed is distance over time.

Find the speed of each trial and then find the average.

Trial 1: v = 0.7 m / 2.5 s = 0.280 m/s

Trial 2: v = 0.7 m / 2.75 s = 0.255 m/s

Trial 3: v = 0.7 m / 2.98 s = 0.235 m/s

v_avg = (0.280 m/s + 0.255 m/s + 0.235 m/s) / 3

v_avg = 0.256 m/s

Round as needed.
