Question 1141642
How long would a day be on Earth if instead of spinning at its usual 1000 mph the Earth rotated at 28,000 mph like the fastest-spinning planet Jupiter?

They have an answer of 52 minutes but don't know how they got the answer.
How would you go about solving?
---------------
Spinning 28 times as fast, not "28 times faster," it takes 1/28 as long to rotate once on its axis/
---> 1/28 of a day --> 1440/28 minutes
==================
PS  The Earth's speed of ~1000 mi/hr is only at the equator.  At the poles, it's zero.
