Question: If a plane travels from 60°W to 60°E, how many hours ahead or behind will it be?
Options:
12 hours ahead
12 hours behind
6 hours ahead
6 hours behind
Correct Answer: 12 hours ahead
Solution:
The total difference is 60° + 60° = 120°, which is 8 hours ahead.

Questions & Step-by-Step Solutions
If a plane travels from 60°W to 60°E, how many hours ahead or behind will it be?
Step 1: Understand that the Earth is divided into 360 degrees of longitude.
Step 2: Know that each 15 degrees of longitude represents 1 hour of time difference.
Step 3: Calculate the total difference in degrees from 60°W to 60°E. This is 60° + 60° = 120°.
Step 4: Divide the total degrees (120°) by 15 to find the time difference in hours. So, 120° ÷ 15°/hour = 8 hours.
Step 5: Since the plane is moving from west to east, it will be 8 hours ahead.
Time Zones – Understanding how longitudinal differences affect time calculations, where each 15° of longitude corresponds to one hour of time difference.
Longitude Calculation – Calculating the total angular distance traveled in degrees when moving from one longitude to another.
