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:

10 squared plus 18 squared equals C squared is the set up
After solving you should get 20.59
