Question

Jenny makes money by mowing lawns. She can mow 8 lawns in 5 hours. At this rate, how long does it take her to mow 12 lawns?

Answer 1

Answer is 20 hours.

Given:

Jenny can make 8 lawns in 5 hours.

The objective is to calculate the time required for her to mow 12 lawns.

Consider the required time as t.

The rate of equation can be represented as,

`\begin{gathered} r=(12)/(8) \\ r=4 \end{gathered}`

Now, the time required can be calculated as,

`\begin{gathered} r=(t)/(5) \\ 4=(t)/(5) \\ t=20\text{ hours} \end{gathered}`

Hence, the time required for her to mow 12 lawns is 20 hours.
