Complex calculation using if, and, median

I'm going to try to write what I am trying to accomplish first in English. I have a formula but something is wrong because it uses the wrong calculation.

I need a formula to check two different cells. If the numbers in those two cells are between 10 and 48 (inclusive) then it is to perform one calculation, if it is outside those then it should perform a slightly different calculation.

Here is what I have:

=IF(AND(F7=MEDIAN(10-48),G7=MEDIAN(10-48)),F5/B8,F5/B8*2)

But when I have numbers that fall in those ranges it is still giving me the false return which is basically double.

I hope that make sense and I'm sure I'm just missing something really simple. I've only recently forayed into using more complex formulas.

I'm not sure that I'm understanding your use of MEDIAN here. Would the following work?

=IF(AND(F7<=48,F7>=10,G7>=10,G7<=48),F5/B8,F5/B8*2)

You are awesome, thank you so much! Dr. Google failed me but eventually he led me here.

Thanks again. These helped greatly. It's a ridiculous worksheet that I've used for the past 4 years and had to manually change the formulas when necessary because I never had the time to sit down and work on it in the past. This just made everything a whole lot easier and solved the problem of the wrong quotes being given when I'm out of the office because other's didn't remember the exceptions to the rules.
