Margarita is driving at the speed of miles per hour. The distance Margarita covers in hours is miles. Give your answer in simplest form.

I'm guessing you want a formula to solve this problem ... ?

The best way to solve this would be in proportions. You have miles over hours like this:

x/y

And then you would have what you're trying to solve for on the other side, and you put them equal to each other:

x/y = a/z

x is the number of miles that you travel in y hours. a is the number of miles you are trying to solve for with the given hour value of z. For example:

Margarita is driving at the speed of 10 miles per hour. The distance Margarita covers in 19.5 hours is a miles. Solve for a.

10/1 = a/19.5

Now crossmultiply:

195 = a
