Answer:
Her speed is 0.39 m/s.
Explanation:
To calculate the speed of something or someone, we need to know the distance traveled and the time taken to do so. According to the instructions, Josephine traveled the distance of 10.7 m. The time she took to do it was 26.8 s. The formula to determine the speed is:
s = d/t
That is, if we divide the distance by time, we find the speed:
s = 10.7/26.8
s = 0.39 m/s
