net gain per day is (3-2) =1 m / day
.
to gain 12 m,, would take 12 days,,,(12 m/1 m/day = 12 days)
.
.
Recognize that on the 10th day, the snail will start at the 9 m level,,and
.
gain 3 m during the day to just reach 12 m.
.
If some sort of platform exists to prevent his sliding back,
.
he could achieve his journey at the end of 10 days .
