Answer:
a.) .375 inches per day
b.) no
c.) 48 days
Step-by-step explanation:
If 8 days produces 3 inches of ice, I divided the 3 inches by the 8 days to see how much it grew per day. I got<u> .375 inches per day</u>.
Knowing how much it grew each day, I used .375 inches per day and multiplied it by 21 (3 weeks). So <u>no, it only grew 7.875 inches over the 21 days</u>.
You can double check it by dividing 10 inches / .375 inches per day and saw it would take over 26 days to reach 10 inches.
I took 1.5 feet and converted it to 18 inches. 18 inches divided by .375 inches per day equals <u>48 days.</u>
I hope this helps you! :)
