Time Zones and Longitude Concepts

This video tutorial explores the concept of time differences based on Earth's rotation and longitude. It explains how the Earth rotates 360 degrees in 24 hours, equating to 15 degrees per hour or 1 degree every 4 minutes. The video discusses the theoretical calculation of time differences between locations based on longitude, using examples of Auckland and Wollongong, and San Francisco and New York. It highlights the difference between theoretical calculations and real-world time zones.

What is the time difference between Auckland and Wollongong based on their longitudes?

• 2 hours

• 1 hour and 40 minutes

A flight leaves San Francisco at 11:30 a.m. and takes 5.5 hours to reach New York. What is the local time in New York when the plane lands?

• 8:12 p.m.

• 4:30 p.m.

• 5:00 p.m.

• 9:00 p.m.

When converting time from San Francisco to New York, how do you adjust the time?

• Add 2 hours

• Subtract 2 hours and 30 minutes

• Subtract 3 hours

• Add 3 hours and 12 minutes
