Question 394.
Given the formula:
[tex]d=rt[/tex]Let's solve for the following:
(a). Solve for r, when:
d = 160 and t = 2.5
To solve for r, rewrite the formula for r.
Divide both sides of the equation by t:
[tex]\begin{gathered} \frac{d}{t}=\frac{rt}{t} \\ \\ \frac{d}{t}=r \\ \\ r=\frac{d}{t} \end{gathered}[/tex]Now, substitute 160 for d and 2.5 for t and solve for r.
We have:
[tex]\begin{gathered} r=\frac{d}{t} \\ \\ r=\frac{160}{2.5} \\ \\ r=64 \end{gathered}[/tex]Therefore, the value of r is 64
