1. STEPS FOR CALCULATING TIME
Read the different statements presented and try to arrange them in the correct order in relation to the steps for calculating time.

2. Understand that the earth rotates from west to east.
Identify the point and time you already have and the one you want to find.
Each rotation of 360 degrees takes 24hrs, therefore 1hr = 15 degrees of longitude.
Draw a number line and mark off the amount of degrees of the given area to check for consistence of the time.

If it is 4 am at 30 degrees E, what time will it be at 90 degrees E?
If it is 5 pm at 35 degrees W, what time will it be at 90 degrees W?
