How to convert Mile per hour to Meter per second
$$\text{Speed}_{\text{ms⁻¹}} = \text{Speed}_{\text{mph}} \cdot 0.44704$$
Examples
Example 1
Convert $30.0\ \text{mph}$ to $\text{ms⁻¹}$.
$$\text{Speed}_{\text{ms⁻¹}} = 30.0 \cdot 0.44704$$
$$\text{Speed}_{\text{ms⁻¹}} = 13.4112$$
$$\therefore \ 30.0\ \text{mph} = 13.4112 \ \text{ms⁻¹}$$
Example 2
Convert $80.0\ \text{mph}$ to $\text{ms⁻¹}$.
$$\text{Speed}_{\text{ms⁻¹}} = 80.0 \cdot 0.44704$$
$$\text{Speed}_{\text{ms⁻¹}} = 35.7632$$
$$\therefore \ 80.0\ \text{mph} = 35.7632 \ \text{ms⁻¹}$$
Example 3
Convert $115.0\ \text{mph}$ to $\text{ms⁻¹}$.
$$\text{Speed}_{\text{ms⁻¹}} = 115.0 \cdot 0.44704$$
$$\text{Speed}_{\text{ms⁻¹}} = 51.4096$$
$$\therefore \ 115.0\ \text{mph} = 51.4096 \ \text{ms⁻¹}$$
Example 4
Convert $150.0\ \text{mph}$ to $\text{ms⁻¹}$.
$$\text{Speed}_{\text{ms⁻¹}} = 150.0 \cdot 0.44704$$
$$\text{Speed}_{\text{ms⁻¹}} = 67.056$$
$$\therefore \ 150.0\ \text{mph} = 67.056 \ \text{ms⁻¹}$$
Example 5
Convert $165.0\ \text{mph}$ to $\text{ms⁻¹}$.
$$\text{Speed}_{\text{ms⁻¹}} = 165.0 \cdot 0.44704$$
$$\text{Speed}_{\text{ms⁻¹}} = 73.7616$$
$$\therefore \ 165.0\ \text{mph} = 73.7616 \ \text{ms⁻¹}$$
