a Frog is at the bottom of a 21 foot well. The frog jumps up 4 feet, and then falls back 2 feet. How many jumps will it take for the frong to jump out of the well?
The frog progresses 2 feet at each jump.
Be careful of the last jump. When the frog jumps up 4 feet, it will be at the top.
10 Jumps Thanks for all your help.
Yea, sry my bad. She's totally correct. By the 9th jump the frog is at 18 feet, 3 feet away. the 10th jump will allow it to free from the well.
