Answer:
17.5 inches
Explanation:
First, we might want to convert feet to inches. If it crawls 2 feet in 1 hour, that means it crawls 24 inches in 60 minutes.
So now, we want to find out how much to divide 60 by. We can do it by finding out how much 24 is divided by to get 7, and then dividing 6 by that so its equal.
24/7=3.42857142857
Now we can divide 60 by that number.
60/3.42857142857=17.5.
So the snail will take 17.5 minutes to crawl 7 inches.
Hope this helps!
