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).
Hello and good evening!
To burn... I believe it has to be 300 degrees celsius or 572 degrees Fahrenheit. What happens is it begins to release combustible gases that ignite when they contact an open flame. The gases burn, gradually raising the temperature of the wood.
I really hope this helps.

It's a homogeneous mixture because when it is mixed together you can no longer tell which parts are chocolate or which parts are milk
