Answer:
B
Step-by-step explanation:
Took the test on AP3X
24* 80/100 = 24*8/10 = 19.2 is the answer.
1647. 1 hour=60 minutes. John can mow 247 square feet per minute, so he can mow 60*247=14820 square feet per hour. 1 yard=3 feet, so 1 square yard =3^2=9 square feet, so in the same duration of time, John can mow 14820/9=1647 square yards (approximately) per hour.
