The total range is 10 minutes.
You are looking for any time that is within 4.75 minutes of the shortest time.
Since it's uniform, that's simply:
4.75 / 10
= 0.475
= 47.5%

Think of the uniform distribution (same probability at each point) as a rectangle over the interval (46, 56).
What proportion of that area would be over the interval (46, 50.75)?
It's a simple proportion problem. With that hint, can you do it now? The solutions is just a bit of arithmetic, so don't over think it.

This is actually impossible, unless she teaches an infinite number of classes !
But never mind. The answer they want is
(50.75  46)/(56  46) = 47.5%
