Time and Distance

The general formula is
D(istance) = R(ate of speed) x T(ime in portions of an hour)

So the question gives you the distance and rate of speed, so what should you do?
Info you're given:
D = 80 miles
R = 50 mph
T = how long does it take

So you need to figure out how to adapt the general formula. I'll bet you can do that part and come up with answer yourself.

I've semi-successfully fought off the notion to introduce Xeno's paradox.

Well then, fight off half of it . . .
