    Put another way....

    13
    44.7
    -7
    55.3

    44.7 is smaller than 55.3

    so try and take one degree and make it 60 minutes:


    12
    104.7
    -7
    55.3
    104.7 - 55.3 = 49.4

    12-7 = 5

    D lat is the difference between 2 latitudes. Therefore if you start off at Lat 13 44.7N and you are traveling to 7 55.3 then first of all you are travelling south. Second, as they are in the same hemisphere deduct one from the other which leaves you with 5 49.4'. Convert whole degrees by multiplying by 60 and you end up with a D lat of 300 + 49.4 = 349.4 South.

    Minutes are just fractions of 60 so you need to get your head around working in a table of 60 to make it easier.

    D long is the same. So try that one yourself.

    Hope this helps

    started a topic Calculating d.(lats, longs), M.(lats,longs)

    Calculating d.(lats, longs), M.(lats,longs)

    This is my first post here and I wanted to ask a question how to calculate those. I am learning in Malta Nautical Institute.
    I understand the concepts of how to find both actually, but the problem is with : lat''A'' 13? 44.7'N lat''B'' 07? 55.3' N and I have to find d.lat. I don`t understand how to do it if it is like 44.7 and 55.3. With seconds added to minute. If I make 44' 42''N and 55' 18''N?
Working...
