Ok This Riddle Will Make You Think

When I first heard this one in high school I got it so wrong I actually got mad at myself

I will now share my frustration with all of you...

A toad is at the bottom of a 20 foot well with very slippery sides.

Once an hour he jumps up three feet but slides back two.

At that rate with no time off for sleep how many hours will it take the toad to get out of the well?

If he jumps 3 ft them slides back 2 ft, only jumps 1 foot every hour so 20 hours

So what's the answer? I got one: a plant on a lake doubles it surface every day. Once it reaches half of the surface of the lake, how many days does it have left until it reaches the surface of the whole lake?

It's not 17. I think everyone who says the frog is up 18 ft at that point doesn't account for the frog sliding backwards before he can jump out. He goes back to 16 feet. So during the 17th hour, he'd only jump to 19 feet instead of the full 20. It's during the 18th hour when this final jump to 20 is realized.

8 hours

18

This is a math word problem, I don't consider it a riddle.

Dude its 17.01 Hours <br />
Every Jump equals 1 foot!<br />
at 17 feet he within 3 feet to the top of the well, his final jump marks the end of the he is out of the well even if he is hanging onto the rim!<br />
Maybe you need to do your math again. As for the water in the well or any other variables you failing to share that would mean you asked for an answer to a question that was not fully formed and you expect a complete answer.<br />
<br />
oh wait maybe we didn't discuss all variables ie. the bucket, water, or the retard that has not answered everyone's post!

60??

he never gets out right????? it says he jumps 3ft then falls 2. but it never says he jumps higher than that. so he never got out right??? what the hell is the answer?!!

1 hour, someone will feel sad for the toad and get him out OR the toad found a random jetpack and fly his way out.

what is it

He stays In the same spot cause if he goes up 3 and goes down 2 he will stay in the same spot. Right?????

Id say 21hours because 20 hours he would be at the top of the wall.

17 hrs, the pore little toad isn't going to wait another hour when one more jump would get it out.

7 hours.....3 feet an hour & everytime he lands his back 2 feet slide back

20 hrs

It's seventeen...when he gets to 17 he won't slide back down because he's out!!

The frog never got anywhere...

I would have never gotten this one.

If the well is twenty feet deep. How high is the water in the well? That was not given in the riddle.

20 hours or 17 hours.

is everyone getti the answer wrong because their not writing hours? if s so than the answer is 20 hours. if im wrong than my second guess is 17 hours.

17 hours

a toad can only jump as high as one foot.... -_-

so if it took 16 hours to get 16 feet, on the 17th hour hed only get up 19 feet.. wouldnt it be on the 18th hour where he jumps 3 feet to jump out??

None of them...toads can't jump

whats the answer

17

its 17 hours

How does a well have 20 foot. Is'nt the measurement unit "feet"
