Kathy and Brian drove a total of 750 miles in 12 hours. Kathy drove the first part of the trip at 65 miles per hour and Brian drove the remaining part of the trip at 55 miles per hour.

This is what you should solve: For what length of time did Kathy and Brian drive?

That is what I got close to, although I think it's the other way around: Kathy 3 hours Brian 9 hours. Thank you!

If Brian drove for 9 hours, he would have gone 495 miles. For Kathy to drive the remaining 255 miles in 3 hours, she'd have to be driving 85 miles per hour.
