Solution: In theory, frogs climb 3 meters and slide 2 meters every day, which is equivalent to frogs climbing 1 meter every day.

So it takes 10÷ 1= 10 days for the frog to get out of the well.

But by the eighth day, the frog had climbed 7 meters, and the frog had climbed 3 meters, so the frog had come out of the well and didn't slide down any more.

So the frog can come out of the well in eight days.

Hope to adopt, thank you!
