The rate traveled is calculated using the formula:


R=(distance)/(time)

From the question, w have the following parameters:


\begin{gathered} distance=140\text{ }miles \\ time=2\text{ }hours \end{gathered}

Therefore, the rate is calculated to be:


\begin{gathered} R=(140)/(2) \\ R=70\text{ miles per hour} \end{gathered}

The correct option is OPTION B.
