Question 287669: What is the time required to cut the grass of a 1,600sf yard where the house is 1,290 sf, at two(2) square feet per second? Answer by unlockmath(1688) (Show Source):
You can put this solution on YOUR website! Hello,
First let's find how much grass there is to cut by subtracting 1290 from 1600.
That gives us 310 sq ft.
Now divide 2 sq ft per minute into 310 sq ft. to give us:
155 seconds
Now if the yard is 1600 st then it would take:
800 seconds or 13 1/3 minutes.
The problem isn't totally clear what is to be cut.
