Fist I want to say HI to all.

and second yes I did searched in the forum and I couldn't find something like I need or maybe I did't know how to look for.

I am trying to create a time formula for my own work i.e

1 to 6 min = .1 (of an Hour)
6 to 12 min = .2
13 to 18 min = .3
19 to 24 min = .4
25 to 30 min = .5
up to one hour

@ 150 an hour

So if I input in one row lets call it time 3 hours I will like in thenext row rate = 450
1.2 hours =180
6.5 hours = 950 etc

any help will be appraciate

Thanks
