What is the speed of a bobsled whose distance-time graph indicates that it traveled 107m in 28s?

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:



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
