Final answer:
To find Jason's unit rate in hours per acre, divide the number of hours it took him to complete the job by the area of the lawn. The unit rate can be written as a complex fraction.
Step-by-step explanation:
To find Jason's unit rate in hours per acre, we need to divide the number of hours it took him to complete the job by the area of the lawn. Let's assume it took him x hours to complete the job and the lawn covers an area of y acres. The unit rate can be calculated as:
Unit rate = x / y
So, to write Jason's mowing rate as a complex fraction, we can write it as x / y. For example, if it took him 5 hours to mow a lawn that covers 2 acres, the unit rate would be 5 / 2.
