Step-by-step explanation:

Step 1: Define

Identify.

$\displaystyle d = rt$

Step 2: Solve for r

1. [Division Property of Equality] Divide t on both sides:                                  $\displaystyle \frac{d}{t} = r$
2. Rewrite:                                                                                                             $\displaystyle r = \frac{d}{t}$
