If the width is 15, and the scale factor from width to length is 3:2, then you will have to divide 15 by 3 to get your original width.
15/3 = 5.
5 is your original width.
The way you can solve this is divide 38 by 5 to find out how many miles you run per minute. In this case, it would be 7.6. Now, for each minute you run, add 7.6 to it and you will have ran 7.5 miles.
Unfortunately I do not know the rectangle you are speaking of, if you could provide the rectangle I would be happy to help.
