How many degrees of longitude correspond to a time difference of 2 hours?

How many degrees of longitude correspond to a time difference of 2 hours?

Step 1: Understand that the Earth is divided into 360 degrees of longitude.
Step 2: Know that the Earth rotates 360 degrees in 24 hours.
Step 3: Calculate how many degrees correspond to 1 hour by dividing 360 degrees by 24 hours: 360 / 24 = 15 degrees.
Step 4: Since we want to find the degrees for a 2-hour time difference, multiply the degrees for 1 hour by 2: 15 degrees * 2 = 30 degrees.
Step 5: Conclude that a time difference of 2 hours corresponds to 30 degrees of longitude.
