Answer :
Final answer:
Maria would take 64 minutes to mow a lawn of 9,600 square feet at a rate of 150 square feet per minute.
Explanation:
The subject in this question is rate, often seen in problems dealing with speed or efficiency.
First, we calculate the total area of the lawn, which is accomplished by multiplying the length (120 feet) by the width (80 feet), resulting in a total area of 9600 square feet. Since Maria mows the lawn at a rate of 150 square feet per minute, we find out how long it takes Maria to mow the whole lawn by dividing the total area by Maria's mowing rate: 9600 / 150 = 64 minutes. Therefore, it would take Maria 64 minutes to mow the lawn.
