Answer
\[R=\frac{D}{T}\].
Work Step by Step
The provided formula is\[D=RT\] and now solve the formula for \[R\]by dividing both the sides by \[T\]
\[\begin{align}
& D=RT \\
& \frac{D}{T}=\frac{R}{{}} \\
& R=\frac{D}{T}
\end{align}\]
The formula \[D=RT\]is for distance traveled, where \[D=\] distance traveled, \[R=\] average speed, and\[T=\] time taken to travel \[D\] distance.
The formula is\[R=\frac{D}{T}\].
