If a car travels 20 miles per hour over a certain distance then travels 30 miles per hour back over the same distance, then what is the average mph that the car travels?

feel free to add some of your own.

25 mph? I don't get it.FragStains

Incorrect.

Let's take a look. If it travels say for 60 miles than using D=RT; 60=20(t) t=30 and 60=30(t) t=20

since the car was moving for a longer period of time going 20 mph the average time will be closer to 20mh than to 30mph, so 25 is not the correct answer.

I'll let you do the rest. 8)

There is a very logical answer to the question.

Diff date of birth? Just 30 mins apart?

EX. June 8th 3505 8:00

June 23rd 3506 8:30

One son was born and 30 minutes later, the other son was born.

If one was born March 2, 1990 at 8:00 then the other March 2, 1991 8:30 then maybe its an answer

They are not twins. Think about the info that was given and then try to figure out what info was not given.

The mother adopted either of both of the sons.someotherguy654

No ,she gave birth to both sons.

It's easy. She concieved a second child a few weeks after the first was concieved. It's happened.FragStains

Wrong.

Technicly you are right. But I am looking for another answer.

I got it! One's a clone. /threadcool_baller

here is the correct answer[spoiler] all her kids were concived on the same day.The riddle does not say that she only had two children. She also had a daughter who was born on the same day . they were triplets , not twins [/spoiler]

The first one sounds like your typical math problem, what's so "brain teasing" about it? Perhaps an explenation in spoiler tag?

I heard one that said "So if you travel back in time, and kill your grandparents, and then come back, who was it that killed your grandparents?"

I don't know if there is even an answer, and I remember someone posting it on OT a few days ago.

A man was talking with another man. The second man said to the first man: "two days ago I was 24 , next year I will be 27"

how is this possible?

[QUOTE="FragStains"]25 mph?I don't get it.evil_dutchman90

Incorrect.

which is 42 in reverse. o.O

Coincidence? I think not!

The man was telling entirely factual info.

two days ago I was 24...is he 25 now?ElArab

That is for you to find out...

Dog years?GTAps2SanA

The riddle says it's a "man", doubt he'd age by dog years, and aren't dog years +7 every year?

It's not a leap year because then he'd be 28...

Maybe this guy has no birth certificate, and he can say what he wants.

he lives on venus, the year is twice as fast.harrisi17

nope
