Answer: The question doesn't explain enough.
160.6 miles per hour (mph)
Explanation:
.029mph is the average speed of a snail.
1. .0568 is the unit conversion for inches to mph.
2. Multiply .0568 by 82 inches to get 4.6576mph
3. Now you can divide its distance of 4.6576 by its average speed of .029mph.
4. 160.6mph is the approximate average time it would take a snail to crawl 82 inches.
5. Not sure what kind of distance your teacher wants the answer in so you can leave in miles per hour or you can find a unit converter on google and change it.
Hope this helps.
