I should probably leave this qs alone

Erm where do I get the seconds from.. That's what I'm confused about.
If you have a Casio calculator press these buttons.

You should obtain 5.462962963.

Now press a button that looks like and this will convert this decimal into hours minutes and seconds.

Ah

5.9 x 10000 / 3 / 60 / 60
=
590 / 3 / 6 / 6
=
295 / 54
=
5 + 25/54

So there are the 5 hours

Then

25/54 x 60
=
250/9
=
27 + 7/9

So there are the 27 minutes

7/9 x 60
=
140/3 = 47 second
