If it is 6 am at 30 degrees W, what time is it at 120 degrees W?
Each 15 degrees of longitude encompasses about one hour of time. Divide the difference between 120 and 30 by 15 to find your answer.
Does this mean to subtract 6 hours from 6 am making it 12:00 pm? Please help I thought it was 1:00 am
