Question

solve the formula $d = rt$ for $t$. a. $t = d - r$ b. $t = rd$ c. $t = \frac{d}{r}$ d. $t = \frac{r}{d}$

Explanation:

Step1: Identify the formula

We have the formula \( d = rt \), and we need to solve for \( t \).

Step2: Isolate \( t \)

To isolate \( t \), we divide both sides of the equation \( d = rt \) by \( r \) (assuming \( r
eq 0 \)).

Dividing both sides by \( r \):

$$ \frac{d}{r}=\frac{rt}{r} $$

Simplifying the right - hand side, since \( \frac{rt}{r}=t \) (the \( r \) terms cancel out), we get:

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

Answer:

C. \( t=\frac{d}{r} \)
