Excel help needed

[Mint_Sauce]

I've done some work, logging the time started and the time finished and now need to add up those times to work out the amount of hours i've worked.

here's a tiny snapshot so you can see what i'm trying to do

start    end      hours
20:00	22:30	2.50 (easy to manually add up)
22:12	01:42	???!
19:24	20:47   ??!?

Can excel takes time differences and convert them to hours? I need to do this so I can then add up the hours column and then do a simple calculation on the final hours and the amount I charge per hour, giving me the total.

Thanks to any excel gurus out there
