If the earth’s rotation is reversed what would be the PST when it is noon at Greenwich?
A
6.3
B
17.3
C
5
D
18:30
Explanation: 

Detailed explanation-1: -When it is noon the time is 12:00; that will be 6:30 A.M.in place of 17:30 P.M. or 5:30 PM. Was this answer helpful?

Detailed explanation-2: -If the Earth suddenly started spinning in the opposite direction, everything not fixed to the ground would be launched at 3200 km/hr eastward. This would happen because everything will still be rotating due to inertia towards the east, while the ground suddenly moves towards the west.

Detailed explanation-3: -With this information, to work out how fast Earth is spinning we need only our planet’s circumference. At the equator, its circumference is roughly 40, 075 kilometres, so dividing this by the length of day means that, at the equator, Earth spins at about 1670 kilometres per hour.

Detailed explanation-4: -Earth makes one complete rotation on its axis every 23 hours and 56 minutes, which is rounded up to 24 hours.

Detailed explanation-5: -Thus, the surface of the earth at the equator moves at a speed of 460 meters per second–or roughly 1, 000 miles per hour.
