Answer:
It takes the frog 7 hours to get out of the well.
Step-by-step explanation:
We know that the well is 11 feet deep and the frog can climb 3 feet per hour.
Each time it climbs, it rests for an hour, and decreases its height by 1 foot.
So, if the frog reaches 3 feet in the first hour, then in the next hour it is 2 feet.
Lets calculate with the same pattern:
1st hour: 3 feet
2nd hour:
feet
3rd hour:
feet
4th hour:
feet
5th hour:
feet
6th hour:
feet
5th hour:
feet
6th hour:
feet
7th hour:
feet
Therefore, it takes the frog 7 hours to get out of the well.
