To determine the average speed we use the formula,

where
and 
Hence, substituting the values we have,

Dividing, we get,

Thus, the average speed of Joshua during that time is 2500 m/h.
Answer:

Step-by-step explanation:
So we have the two functions:

And we want to find f(g(-2)).
First, let's find g(-2):

Multiply:

Subtract:

Now, substitute:

Now, find the value of f(-20):

Multiply:

Add:

So:

And we're done!
