Question

question 10 of 25
the formula d = rt means that the distance traveled is equal to the rate (speed) times the time.
solve d = rt for r.
a. r = dt
b. r = \frac{d}{t}
c. r = \frac{t}{d}
d. r = d - t

Explanation:

Step1: Isolate the variable r

Given $d = rt$, divide both sides by t.
$\frac{d}{t}=\frac{rt}{t}$

Step2: Simplify the right - hand side

Since $\frac{rt}{t}=r$ (t≠0), we get $r=\frac{d}{t}$.

Answer:

B. $r = \frac{d}{t}$
