Approximately 4 minutes.
Once around in a day is 360 degrees, so one degree is 1/360 of a day. 24 hours x 60 minutes = 1,440 minutes per day, 1,440 / 360 = 4.

The Earth rotates as quickly as each and every 24 hours. There are 360 levels of longitude on earth so divide 360 via 24 = 15 levels in line with hour. Then set up a mathematical relationship and you will get 4 minutes in line with a million degree of longitude.

At any stationary point on the surface of the Earth, that point rotates a full circle in exactly one day, since for all intents and purposes the Earth is a perfect sphere and the Earth rotates about its axis.
You know there are 360 degrees in a circle. From Wikipedia, a day is exactly 23 hours, 56 minutes, and 4.091seconds. Convert that to minutes: one day is 1436.06818333 minutes. So every point on the Earth moves exactly one degree in:
1436.06818333 minutes/1 day * 1 day/360 degrees = 3.9891 minutes, or almost 4 minutes.
Well, that's not quite correct. The Earth’s diameter is 3963 miles. That means a point on the equator is 1 Earth’s radius from the axis of rotation. Here, the point travels the circumference of the circle in one day, or 2*pi*3963 = 24900 miles. In 4 minutes, that point will travel 69 miles (1 degree). As you get closer to the poles, the radius to axis get smaller, which means the distance a point travels is less than the point on the equator. A point roughly in northern Greenland is only about ½ Earth’s radius from the axis of rotation. That means that point only travels about 35 miles in 4 minutes. That point is actually rotating at ½ the speed a point on the Equator is rotating!
This trend continues until you hit the axis itself, defined by the North and South poles. If you stood 1 foot away from the North Pole, it would take all 24 hours of the day to go around a circle 1 foot in radius. Therefore, every point on the Earth rotates around the N-S axis, except for two. At the North pole itself, the Earth does not rotate. By definition, the exact point that is the North pole does not experience a day. Same thing with the South Pole. Likewise, at that exact point, the only direction you can travel is South.
Probably more than you wanted to know.

Ok, here is how you figure it out. There are 360 degrees in a circle and it takes the earth 24 hours to rotate all 360 degrees. So 24/360 = .06666667. Now remember that this answer is in hours. Multiply it by 60 to get the answer in minutes: .06666667 x 60 = 4. So 4 minutes is the answer.

Several of the listed answers are wrong. The earth rotates through fifteen degrees every hour. 15x24=360. That is a degree every 4 minutes. Just by knowing this I have been able to calculate my longitude with surprising accuracy using just a stick to measure the suns shadow and determine local noon, and a wristwatch set to Greenwich mean time. Figure out the difference between the two in minutes and divide by four. It the answer exceeds 180 you're in East longitude. Subtract the amount exceeding 180 from 180 and bingo. I have a way of determining latitude too. I use a protractor for this, and although I could make one out of a piece of paper, I like the protractor as it fits well in my pocket protector and looks good with my collection of multicolored pens.

I bet you tried. Sure. ;-)
degrees for a full circle? 360
time it takes? 24 hours (also called a day), or 1'440 minutes.
minutes to rotate one degree? 1'440/360 = 4 minutes
happy to help but suggest you try, once in a while, to think a couple minutes on problems, especially as simple as this one. This may prove helpful in a great many situations in life, not just questions from school! ;-)

The woman was right(sorry not being derogatory, just could'nt remember your random name). The earth is a sphere and fully rotates every 24 hours. For a sphere to fully rotate it must turn 360 degrees.
360/24=1/30th of an hour
1/30th of an hour is equal to 2 mins.

There are 360 degrees in one rotation each day. There are 1440 minutes in a day. Divide and you get 4 minutes.

take the earths circumference at the equater
then dived that by 360 I think it comes out to 77 miles per degree of longitude. That's useless info
multiply 60 seconds x 60 minutes x 24
divide that number by 360 then you have the time in seconds how long it takes
hope this helps

Two minutes, or one 360th of a day.
