Well firstly 45min = 450nm is not going to happen, lets pick .85 as a typical CRZ m no. which is around 490kts, or at your given 45min about 370nm. UNLESS you cruize around at 10nm/min, in which case your numbers are right.
The other point that I am NOT SURE about is the 45min itself. Your mob may have a different fit, but from memory the -400's I have flown have about 5.2t capacity, which is not 45min worth of fuel.
<Edited re. Spanners post - Thx - looks like memory doesn't serve after all. I must have been thinking of the 5.2 ratio of HST to CWT... or maybe just too long on the crack pipe last night>
