Well to solve this firstly we should calculate her average speed while she was going to work. Which comes out to be 45 miles per hour.
Now if her average speed while going home is half as fast as while coming to work was, the answer would be 22.5 miles per hour. So the average speed for the total journey would be the average for these two values. As the distance was same for both the journeys we can simply do 45 + 22.5 / 2 = 33.75 mph.

Answer:
657 pounds
Step-by-step explanation:
Given
Represent the amount of fertilizer with x and the yield with y.
So, we have:
Required:
Determine the yield (y) when fertilizer (x) is 73ft^3
Using linear interpolation, we have:
Substitute the x and y values using
and ;
We have:
Open bracket
To solve for y when x = 73.
We simply substitute 73 for x
<em>Hence, the yield for 73 cubic feet is 657 pounds</em>
