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: [tex]3-1=2[/tex] feet
3rd hour: [tex]2+3=5[/tex] feet
4th hour: [tex]5-1=4[/tex] feet
5th hour: [tex]4 +3= 7[/tex] feet
6th hour: [tex]7-1=6[/tex] feet
5th hour: [tex]6+3=9[/tex] feet
6th hour: [tex]9-1=8[/tex] feet
7th hour: [tex]8+3= 11[/tex] feet
Therefore, it takes the frog 7 hours to get out of the well.
