A.0.35
B.0.24
C.0.03
D.0.01

Respuesta :

The correct answer is C) 0.03.

1 square yard is a square whose sides are all 1 yard in length.  1 yard = 3 feet, so each side of this square is 3 ft; this gives us 1 yd² = 3(3) = 9 ft².  This gives us 15/9 = 1.67 yd²/min.

1 minute = 60 seconds; this gives us 1.67*60 = 0.027 ≈ 0.03 yd²/sec

Answer:

c. .03 in the answer 1 yard=9 sq ft so 15/9=1.66 and then 1.66/60 seconds = .027 so the closest answer is .03
