Question

John mows 280 square feet of lawn per minute. How many square yards of lawn does he mow per hour?

Answer 1

ANSWER: John mows 1866.67 square yards per hour. 

 

Figure out how many square feet he mows in an hour:

 

280*60=16800 sq ft/hour

 

Now convert square feet into square yards. The important thing to remember here is that one square yard is 3 feet on each side. Therefore, one square yard consists of 9 square feet (3*3)

 

So he mows 16800 square feet in one hour. Divide this by 9 to convert it into square yards. 

 

16800/9=1866.67 square yards

 

So he mows 1866.67 square yards per hour and that is the answer.
