How fast would you say the Earth rotates near the equator?

Question

I'm so freaking behind in school. I don't even know what an equator is. XD <3

Then again, this is suppose to be a question in a game for highschoolers. I'm only just entering middle school. Or maybe I am just really dumb.. xD

The answers can either be;

"About 420 km/hour."

"About 850 km/hour."

"About 1,700 km/hour."

Please only answer if you're sure~~!

Answer 1

The earth rotates once a day.  At the equator the earth is roughly 25,000 miles in circumference.  24 hrs a day/25,000 miles = a little over 1,000 mph.  A mile is longer than a km so the only answer that works would be 1,700

Answer 2

Well, consider - the Earth&#039;s about 24,900 miles around at the equator, and it rotates once in 24 hours (That means, the sun gets back to the same longitude in 24 hours) so, it&#039;s a little faster than 1000 MPH.  

Answer 3

The circumference of the earth at the equator is 60 x 360 = 21600 nautical miles. Thus the speed of rotation = 21600/24 = 900 nautical miles per hour or 1035 statute mile per hour. That would be 1666 km/hr or about 1700km/hr

Answer 4

The reference number is 469 m/s or more correct 1688.84 km/h

Answer 5

So if the Earth is a ball, and you cut it horizontally in half in the middle, that&#039;s the equator.  Please don&#039;t cut the Earth in half - i still live there.

The Earth is about 25,000 miles in diameter, and rotates once a day, say 24 hours.  So that&#039;s a hair over 1000 miles per hour.  It&#039;s a little more than 1.6 km/mile, so it must be about 1,700 km/hour.

The only things i knew off the top of my head was the circumference of the Earth and more or less the size of a mile in km.  But you could just look it up in Wikipedia.  Oh, and convert m/s to km/hour.

Answer 6

About 40,000 km/24 hour.

So divide 40,000 by 24.  

That&#039;s around 1667 km/hour.
