## Minutes and Seconds in Latitude and Longitude

this video is going to look at the idea

of minutes and seconds as it relates to

latitude and longitude this can be

confusing for some people because we

know of minutes and seconds in relation

to time and there is a slight connection

with time but we should just try to

think of this as something separate to

what we already know about minutes and

seconds if you're not sure about how

latitude and longitude work together you

should watch the previous video about

that in that video we saw that in

between 41 degrees north and 42 degrees

north there's actually a hundred and

eleven kilometers difference so if I was

at sea and told somebody that I was at

41 degrees north it would be very

unhelpful for somebody who was trying to

find out exactly where I was to make

this more precise we break down each

degree into 60 separate parts and each

one sixtieth of a degree is called one

minute so if we were to break up the

distance between 41 degrees north and 42

degrees north into 60 equal parts the

one that we ran straight through the

middle so if we're at 41 and a half

degrees north we would call that 41

degrees and 30 minutes north and this is

the way which we would write that just

like 30 minutes is half of an hour 30

minutes is half of a degree in latitude

we said the distance between 41 and 42

degrees north was 111 kilometers the

distance between 41 degrees and 30

minutes and 41 degrees and 31 minutes so

if we had just one minute separate we

would have a distance of one point eight

five kilometers between each line

that is much more precise but we've be

even more precise in that we break each

minute down into 60 equal parts and not

surprising we would call each one of

those one second so 60 seconds make up

one minute so if we were a quarter of

the way between 41 degrees and 30

minutes and 41 degrees and 31 minutes a

quarter of one minute would be 15

seconds and we would write that like

this so this is saying that the

coordinates are 41 degrees 30 minutes

and 15 seconds north so this is the

location of Sydney it is at 33 degrees

52 minutes and four seconds south and

151 degrees 12 minutes and 23 seconds

east the most important thing that we

want to be aware of here is that the way

that we express this latitude is in this

way with the degree sign with the one

line for the minutes and the two line

for the seconds and the same again with

the longitude
