    The best I can say is you need to divide them, 90/2=45

    If you divide each of them, what is the number you get each time?

    constant of proportionality - the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality \[90 = 2k\]\[135 = 3k\]etc, etc So we know that 45 is the factor of proportionality, which is the first part of your problem. The unit rate is one over the factor of proportionality, so it would be 1/45 (45 miles per hour)

    or would it be 45/1?

    Yes, it is 45/1\[\frac{ 45 miles }{ 1 hour }\] So now all you have to do is write an equation representing the rate.

    IT WOULD BE 1/45 RIGHT

    No, it is 45/1. I made a mistake.
