Answer:

After 5 minutes Kaitlyn have to mow 5,250 square feet of lawn.

Step-by-step explanation:

We are given the following in the question:

Total area of lawn = 5,625 square feet

Rate of mowing lawn = 75 square feet each minute

Area of lawn mowed in 5  minutes =

=\text{Rate of mowing lawn}\times \text{Time}\\=75\times 5\\=375\text{ square feet}

Square feet does Kaitlyn still have to mow after 5 minutes

Thus, after 5 minutes Kaitlyn have to mow 5,250 square feet of lawn.
