Answer:
19.39mph
Explanation:
To calculate speed, the formula; distance (d)/time(t) is used.
In this question, a distance of 40yards and a time of 4.22seconds is given. We need to convert the distance to miles and time to hours.
If 3600s = 1 hr
Then 4.22s will be 4.22/3600 hours
= 0.001172hours.
If 1760 yd = 1 mile
Then 40 yd will be 40/1760 miles
= 0.02272miles
Hence, the speed in miles per hour (mph) = 0.02272miles ÷ 0.001172hours
= 0.02272 ÷ 0.001172
= 19.38566
= 19.39
Therefore, the speed of the player is 19.39 miles per hour (mph).
