Step-by-step explanation:
Let be "x" the time in minutes that will take him to mow the entire park.
You know that he can mow 13 square feet in 1 minute and he has to mow 14,623 square feet.
Then, you can write the following proportion:
Solving for "x", you get:
To write that improper fraction as a mixed number:
- The quotient when you divide the numerator by the denominator of the fraction obtained, is (This will be the whole number).
- The remainder of that division is (This will be the numerator of the fraction).
- The denominator does not change.
Then:
Parameterize the line segment 
by
where![t\in[0,1]](https://tex.z-dn.net/?f=t%5Cin%5B0%2C1%5D)
. Then
So the integral is
where
So the integral is
