In latitude 50° 10' N, the departure between two meridians is 360 nautical miles. What is the Difference of Longitude?
GIVEN:
Latitude = 50° 10'
Departure = 360 nm
WHAT IS ASKED: Difference of longitude
SOLUTION:
This is the formula in solving for the difference of longitude:
Dlo = (Dep/Cos lat) ÷ 60
Step 1. Divide the departure by Cosine latitude.
360 ÷ Cos 50° 10' = 562 nm
Step 2. Divide the answer of step 1by 60 to convert it into degrees.
562 ÷ 60 = 9° 22' is the difference of longitude (Dlo).
