How to convert Foot per minute to Mile per hour
$$\text{Speed}_{\text{mph}} = \frac{\text{Speed}_{\text{ft/min}}}{88}$$
Examples
Example 1
Convert $40.0\ \text{ft/min}$ to $\text{mph}$.
$$\text{Speed}_{\text{mph}} = \frac{40.0}{88}$$
$$\text{Speed}_{\text{mph}} = 0.454545$$
$$\therefore \ 40.0\ \text{ft/min} = 0.454545 \ \text{mph}$$
Example 2
Convert $90.0\ \text{ft/min}$ to $\text{mph}$.
$$\text{Speed}_{\text{mph}} = \frac{90.0}{88}$$
$$\text{Speed}_{\text{mph}} = 1.022727$$
$$\therefore \ 90.0\ \text{ft/min} = 1.022727 \ \text{mph}$$
Example 3
Convert $115.0\ \text{ft/min}$ to $\text{mph}$.
$$\text{Speed}_{\text{mph}} = \frac{115.0}{88}$$
$$\text{Speed}_{\text{mph}} = 1.306818$$
$$\therefore \ 115.0\ \text{ft/min} = 1.306818 \ \text{mph}$$
Example 4
Convert $140.0\ \text{ft/min}$ to $\text{mph}$.
$$\text{Speed}_{\text{mph}} = \frac{140.0}{88}$$
$$\text{Speed}_{\text{mph}} = 1.590909$$
$$\therefore \ 140.0\ \text{ft/min} = 1.590909 \ \text{mph}$$
Example 5
Convert $170.0\ \text{ft/min}$ to $\text{mph}$.
$$\text{Speed}_{\text{mph}} = \frac{170.0}{88}$$
$$\text{Speed}_{\text{mph}} = 1.931818$$
$$\therefore \ 170.0\ \text{ft/min} = 1.931818 \ \text{mph}$$
