if each time zone is 15 degrees in width who many time zones are there around the earth?
Simple math problem. There are 360 degrees around the world. Divide 360 by 15.
To determine the number of time zones around the Earth, you need to divide the total degrees (360) by the width of each time zone (15).
The calculation is as follows:
360 degrees / 15 degrees = 24 time zones
Therefore, there are 24 time zones around the Earth.
