Question

Michael can mow 5 lawns in 36 minutes. At this rate, how long will it take him to mow 15 lawns?

Answer 1

Answer:

It would take him 108 minutes to mow the lawn.

Step-by-step explanation:

We can do proportion.

$\frac{5 \: lawns}{36 \: minutes} = \: \frac{15 \: lawns}{x}$

$36 \times 15 = 540 \\ 5 \times x = 5x$

$\frac{540}{5} = \frac{5x}{5}$

$108 = x$
