Answer: 
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:
C=10 & P=5
3C+4P=50
C+P=15
Solve
3C+4P=50
3C+3P=45
Subtract
P=5
Substitute in equation 2
C+P=15
C+5=15
C=10
