How to convert Mile per hour to Mile per second
$$\text{Speed}_{\text{mi/s}} = \frac{\text{Speed}_{\text{mph}}}{3600}$$
Examples
Example 1
Convert $45.0\ \text{mph}$ to $\text{mi/s}$.
$$\text{Speed}_{\text{mi/s}} = \frac{45.0}{3600}$$
$$\text{Speed}_{\text{mi/s}} = 0.0125$$
$$\therefore \ 45.0\ \text{mph} = 0.0125 \ \text{mi/s}$$
Example 2
Convert $60.0\ \text{mph}$ to $\text{mi/s}$.
$$\text{Speed}_{\text{mi/s}} = \frac{60.0}{3600}$$
$$\text{Speed}_{\text{mi/s}} = 0.016667$$
$$\therefore \ 60.0\ \text{mph} = 0.016667 \ \text{mi/s}$$
Example 3
Convert $120.0\ \text{mph}$ to $\text{mi/s}$.
$$\text{Speed}_{\text{mi/s}} = \frac{120.0}{3600}$$
$$\text{Speed}_{\text{mi/s}} = 0.033333$$
$$\therefore \ 120.0\ \text{mph} = 0.033333 \ \text{mi/s}$$
Example 4
Convert $140.0\ \text{mph}$ to $\text{mi/s}$.
$$\text{Speed}_{\text{mi/s}} = \frac{140.0}{3600}$$
$$\text{Speed}_{\text{mi/s}} = 0.038889$$
$$\therefore \ 140.0\ \text{mph} = 0.038889 \ \text{mi/s}$$
Example 5
Convert $170.0\ \text{mph}$ to $\text{mi/s}$.
$$\text{Speed}_{\text{mi/s}} = \frac{170.0}{3600}$$
$$\text{Speed}_{\text{mi/s}} = 0.047222$$
$$\therefore \ 170.0\ \text{mph} = 0.047222 \ \text{mi/s}$$
