We can use the equation n/2 = h

n = the number of lawns Chandler mows.

h = the number of hours he spent.

Lets fill in for n since he mowed 7 lawns.

7/2 = h

3.5 = h

If you want to turn it into a timely fashion: 3.5 = 3 hours 30 minutes.

So, it took Chandler 3 hours and 30 minutes to mow 7 lawns.
