The frog

Mon Dec 07, 2015 12:03 pm  by GmdAquaman

[quote][u][i][b][size=24][color=darkred]A frog is at the bottom of a 30 meter well. Each day he summons enough energy for one 3 meter leap up the well. Exhausted, he then hangs there for the rest of the day. At night, while he is asleep, he slips 2 meters backwards. How many days does it take him to escape from the well?

Note: Assume after the first leap that his hind legs are exactly three meters up the well. His hind legs must clear the well for him to escape.[/color][/size][/b][/i][/u][/quote] :D :) :( :o :shock: :? :lol: :x :P :oops: :cry: :evil: :twisted: :roll: :wink: :!: :?: :arrow:
