Question

no additional details

Answer 1

3 ft = 1 yard.

Squaring, 9 sq ft = 1 sq yd.

So to get 600 sq ft into square yards, use 1/9 as a multiplier, i.e. 600 sq ft = 600/9 sq yds.

Do the division & call me in the morning!

Answer 2

We know that 1 yd = 3 ft, so 1 yd² = 3² ft² = 9 ft².

 

Also 1 hr = 60 min.

 

If the tractor can plow 600 ft² in 1 min., then it can plow

 

60(600) ft² in 60 min. or 1 hr

 

= 36,000 ft² in 1 hr

 

How many square yards are in 36,000 ft²? Divide 36,000/9 = 4,000 yd²
