1 Time ZonesThe World is divided up into 24 time zones. Each time zone is approximately15 degrees of longitude wide. The time within each time zone has the samestandard time.
5 Global Time Zones:1. To calculate the difference in time between two places you need to know:a) that there are 15 degrees in an hourb) the difference in the degrees of longitude between the two placesc) what time it is at the initial locationd) All of the abovee) none of the above.2. The purpose of the International Date Line is:a) to make time zone calculations confusingb) so that no two neighboring cities are one day apart in timec) to have a set origin to start at when doing time zone calculationsd) to make sure that times are the same at equal distances from the equatore) so that the day gets later the further west you travel.3.
