Very important fact, that comes up in hundreds of situations . . . . . We never feel motion.
We only feel changes in motion.
Example: You can read or sleep very well in a car going 70 miles an hour, as long as the
car doesn't speed up, slow down, turn, or hit a rough spot. And have you ever been on
an airliner, cruising along at 400 miles an hour while you read a book or take a nap ?
It makes no difference whether you're moving fast or slow, horizontally or vertically.
You feel nothing until either the speed or the direction changes.
On the spinning earth, you're moving almost 1,040 miles an hour at the equator, or
730 miles an hour at the latitude of Chicago. You don't feel the speed in the direction
east along the ground, because it never changes. You do feel the force it takes to
keep you moving in a circle at that speed ... the force you call your "weight".
Earth's rotation is from west to east. When launching satellites, it's more convenient to launch in the same direction, to take advantage of this initial impulse, and thus save energy - since the satellite must have a certain speed in order to orbit Earth. To have a satellite from east to west would require an additional speed (with respect to Earth's surface) of twice the speed of Earth's rotation, which is about 1600 km/hour at the equator.
The equator is due south from Mazatlan. Conversely, Mazatlan is almost 2600 kilometers (1600 miles) north of the equator.
The tropics is the area of Earth surrounding the equator. It extends from about 23.5 degrees (1600 miles) north of the equator to about 23.5 degrees (1600 miles) south. This is from about Durango, Mexico to the middle of Bolivia.
It is north of such tropic.The Tropic of Cancer passes through Mexico.

i dont really know but if you were in a 50 mile radius in the circumference of the earth i think it will take an hour

Interestingly, MOST things in our solar system spin that way; counter-clockwise as seen from a location high above the north pole. All the planets orbit that way; most of the planets SPIN that way. (Venus hardly spins at all, but is backwards, while Neptune's spin axis is nearly parallel to the ecliptic.) So does the Sun itself. We can't be certain as to the cause, but it seems likely that the original nebula that collapsed to form the Sun and our solar system was spinning that way, and that the physical law of "conservation of angular momentum" kept everything moving that way. I suspect that when we visit other solar systems, we will find that everything in a solar system spins the same direction, but that on average, their spins will be sort-of evenly distributed.

The equator is due south from Mazatlan. Conversely, Mazatlan is almost 2600 kilometers (1600 miles) north of the equator.
Aside from spinning on its axis, the Earth also revolves around the sun, which takes a whole year (365 days). The spinning of the Earth depends on the latitude of the Earth. At the equator, the Earth spins at a speed of about 1,000 miles per hour.
The maximum speed of the 1962 Porsche 1600 s 4cyl 90hp is 100 mph.
The PC speed rating that matches up with DDR3-1600 RAM is PC3-12800. This designation indicates that the RAM operates at a maximum bandwidth of 12,800 MB/s. The "1600" in DDR3-1600 refers to the memory clock speed of 1600 MHz, which is consistent with the PC3-12800 rating.
The maximum speed of the Porsche 1600 s 4cyl 75hp 1962 is 175 km/h .
1500 rpm.
For rotation: The circumference of the earth is approximately 40041.47km, and this distance is covered in exactly 86400 seconds (the number of seconds in a day). Therefore, the earth turns at around .46344km in a second, or 1668.39km/h (or 1036.69mph). For revolution around the sun: The earth orbit's radius is 1AU or 150000000km. Multiplying by 2*PI gives us a circumference of around 942477796km. This distance is covered in 365.24 days, or 31556736 seconds. So the earth revolves at a speed of 29.87km/s or 107518km/h (or 66808.59mph). Check links for a source for the above. [Footnote: the 24 hour rotation is the synodic (relative to the sun) rotation of the earth. In fact, the earth completes one absolute sidereal rotation in slightly less time: 23 hours 56 minutes and 4 seconds, so relative to the fixed stars, the earth is rotating slightly faster than the figure given above.]
It is about 2600 km, or about 1600 miles North of the equator. It represents the most northerly position where the sun appears overhead in June of each year. It is just more than 23 degrees north of the equator.
