If the Earth were to spin twice as fast as it does now, how many hours would be in one day (one complete spin)?

if the eart were to spin twice as fast, gravity could not hold us to it, causing us to be slung into space resulting in the death of every life form.

Explanation:

At 100 mph faster, the equator would start to drown. ... If we double the speed at the equator, so that Earth spins 1000 miles faster, "it would clearly be a disaster," says Fraczek. The centrifugal force would pull hundreds of feet of water toward the Earth's waistline. There would only be 12 hours.
