Calculating the Time for the Snail to Climb the 20-Meter Log

To calculate the number of days it will take for the snail to climb a 20-meter log, we can use the following approach:

1. Calculate the net distance covered by the snail each day, considering its ascent and descent. 2. Divide the total height of the log by the net distance covered by the snail each day to find the number of days required.

Calculation

The snail climbs 3 meters up and then slips 2 meters down, resulting in a net progress of 1 meter per day.

Therefore, to climb a 20-meter log, the snail will take 20 days.

This calculation is based on the fact that the snail climbs 3 meters and then slips 2 meters, resulting in a net progress of 1 meter per day
