Answer:
It will take the snail 10 days to climb out of a 20-meter hole if it climbs 4 meters during the day and slides back 2 meters at night.
Step-by-step explanation:
To calculate the number of days it will take the snail to get out of the hole, we need to consider the net progress the snail makes each day.
During the day, the snail climbs 4 meters, but at night it slides back 2 meters. Therefore, the snail makes a net progress of 4 meters - 2 meters = 2 meters per day.
Since the snail has to climb a total of 20 meters to get out of the hole (assuming it was dropped at the bottom of a 20-meter hole), we can calculate the number of days it will take by dividing the total distance by the net progress per day:
Number of days = Total distance / Net progress per day
Number of days = 20 meters / 2 meters per day
Number of days = 10 days
I hope it helps you, good luck!
