Can we say 1.3 times faster than the truck, or 78 mph?
Yes, exactly.
Except the trailer is still going the same speed, but comparing the rpms of the wheel, to something everyone can grasp (mph) is accurate.
Like mooky said, them 10" snomachine/pontoon boat trailer wheels hold up reasonably well at higher highway speeds, although not near as well as larger diameter tires.
PS, the 45mph uhaul max was/is to keep people who don't tow much, driving slower, IE less accidents and liability. Nothing to do with the trailer being able to not go faster without coming apart.
