Algebra word problem

J left the house at 8:12 am on Tuesday to procter an exam beginning at 10 am. The weather was clear and sunny; the roads were clear and dry. It took her 1 hour and 45 minutes to drive the 45 highway miles to her destination. (This is usually a 45-minute trip.)

If J. has to make the same trip on Friday, to be ready to procter at 9 am, at what time must she leave the house, assuming that the roads are moderately sloppy (it's been snowing all day on Thursday)? What role does the "Friday-before-Christmas" time frame play? (Might be beneficial - people take the day off, less traffic. Might be devastating - pent up shopping demand from all this snow leads to record traffic jams.)

Post answers in the comments. Partial credit will be given if you show your work. (Yeah, I'm a softie.)

I'm confused about this blog. I thought it was a travel site, not a math-prep one. Anyway, I'd travel up to 3 hours for really good latkes, don't
ya know!
