Calculating the Snail's Journey to the Top of the Tree

To calculate the time it takes for the snail to reach the top of the tree, we need to consider its daily progress and the height of the tree.

- The snail starts its journey at 7 AM and crawls for 8 hours, covering 4 meters each day. - After crawling for 8 hours, it falls asleep and then slides down 2 meters during the night.

Given the height of the tree is 9 meters, we can calculate the number of days and hours it will take for the snail to reach the top.

Calculation

- The snail's net progress each day is 4 meters (day) - 2 meters (night) = 2 meters per day. - To reach a height of 9 meters, the snail will need 9 meters / 2 meters per day = 4.5 days.

Since the snail can't crawl for half a day, it will take the snail 5 full days to reach the top of the tree.

Therefore, it will take the snail 5 days to reach the top of the tree.
