Question: If a plane travels from a location at 60°E to 120°E, how many time zones does it cross? (2023)

Options:

Correct Answer: 3

Exam Year: 2023

Solution:

The time difference is (120° - 60°) / 15° = 4 hours, which corresponds to crossing 3 time zones.

If a plane travels from a location at 60°E to 120°E, how many time zones does it cross? (2023)

If a plane travels from a location at 60°E to 120°E, how many time zones does it cross? (2023)

Step 1: Identify the starting longitude, which is 60°E.
Step 2: Identify the ending longitude, which is 120°E.
Step 3: Calculate the difference in degrees between the two longitudes: 120°E - 60°E = 60°.
Step 4: Understand that each time zone corresponds to 15 degrees of longitude.
Step 5: Divide the total degree difference by the degrees per time zone: 60° / 15° = 4.
Step 6: Since the plane crosses from one time zone to another, subtract 1 from the total: 4 - 1 = 3 time zones crossed.

Time Zones – Understanding that each time zone typically spans 15 degrees of longitude, corresponding to one hour of time difference.
Longitude Calculation – Calculating the difference in longitude to determine the number of time zones crossed.
