The answer is 3.82m/s.
Speed is the distance traveled over a period of time. If you put that into a formula it will look like this:
[tex]s= \frac{d}{t} [/tex]
Where:
s = speed
d = distance
t = time
Now your given would be:
m = 107m
t = 28s
All you need to do is input the given into the formula and you will be able to calculate the answer:
[tex]s= \frac{d}{t} [/tex]
[tex]s= \frac{107m}{28s} [/tex]
[tex]s= 3.82m/s [/tex]
