Question

Solve for r. Use the formula: d = rtWhen d=160 and t=2.5

Answer 1

Question 394.

Given the formula:

`d=rt`

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:

`\begin{gathered} (d)/(t)=(rt)/(t) \\ \\ (d)/(t)=r \\ \\ r=(d)/(t) \end{gathered}`

Now, substitute 160 for d and 2.5 for t and solve for r.

We have:

`\begin{gathered} r=(d)/(t) \\ \\ r=(160)/(2.5) \\ \\ r=64 \end{gathered}`

Therefore, the value of r is 64
