Answer:
<h2>D. 5 hours</h2>
Step-by-step explanation:
rt=d
rt+rt=900
80t+100t=900
180t=900
18t=90
2t=10
t=5
5 hours
80*5+100*5=900
It would be about three, as 700 times three is the closest you can get out of the options to 2400 square feet without going over. If it was about 4, it'd be 2800 feet, and there's not enough room.
Hopefully this helps!
