Distance equals rate times time, or 



*[tex \LARGE \ \ \ \ \ \ \ \ \ \ d\ =\ rt]


Multiply both sides of the equation by *[tex \Large \frac{1}{t}]:



*[tex \LARGE \ \ \ \ \ \ \ \ \ \ r\ =\ \frac{d}{t}]


Substitute your values and do the arithmetic:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ r\ =\ \frac{30}{1.5}]


You get to do your own arithmetic.
