Myra lives in a city located on longitude 36 degrees East, and her watch shows 6 pm. She needs to visit her friend Naira, whose city lies on 43 degrees East. What will be the time on Naira's watch?

• 6:32 PM

• 6:30 PM

• 6:28 PM

• 6:40 PM

Answer explanation

Understanding the problem:

• Your longitude: 36 degrees East

• Your friend's longitude: 43 degrees East

• Time difference between two longitudes: 4 minutes

• Your current time: 6 PM

Calculation:

• Difference in longitudes = 43 degrees East - 36 degrees East = 7 degrees

• Time difference = 7 degrees * 4 minutes/degree = 28 minutes

Determining the time at your friend's place:

Since your friend's city is located at a longitude east of yours, the time there will be later.

• Time at your friend's place = Your time + Time difference

• Time at your friend's place = 6 PM + 28 minutes = 6:28 PM

So, the time at your friend's place is 6:28 PM.
