Convert Speed of sound rounded to Kilometer per minute
Unit definitions
Speed of sound rounded
The speed of sound is frequently rounded to $340\ \text{m/s}$ in introductory physics calculations.
Kilometer per minute
Kilometer per minute is the distance traveled in kilometers in one minute.
How to convert Speed of sound rounded to Kilometer per minute
$$\text{Speed}_{\text{km/min}} = \text{Speed}_{\text{Speed of sound}} \cdot 20.4$$
Examples
Example 1
Convert $50.0\ \text{Speed of sound}$ to $\text{km/min}$.
$$\text{Speed}_{\text{km/min}} = 50.0 \cdot 20.4$$
$$\text{Speed}_{\text{km/min}} = 1020$$
$$\therefore \ 50.0\ \text{Speed of sound} = 1020 \ \text{km/min}$$
Example 2
Convert $65.0\ \text{Speed of sound}$ to $\text{km/min}$.
$$\text{Speed}_{\text{km/min}} = 65.0 \cdot 20.4$$
$$\text{Speed}_{\text{km/min}} = 1326$$
$$\therefore \ 65.0\ \text{Speed of sound} = 1326 \ \text{km/min}$$
Example 3
Convert $120.0\ \text{Speed of sound}$ to $\text{km/min}$.
$$\text{Speed}_{\text{km/min}} = 120.0 \cdot 20.4$$
$$\text{Speed}_{\text{km/min}} = 2448$$
$$\therefore \ 120.0\ \text{Speed of sound} = 2448 \ \text{km/min}$$
Example 4
Convert $135.0\ \text{Speed of sound}$ to $\text{km/min}$.
$$\text{Speed}_{\text{km/min}} = 135.0 \cdot 20.4$$
$$\text{Speed}_{\text{km/min}} = 2754$$
$$\therefore \ 135.0\ \text{Speed of sound} = 2754 \ \text{km/min}$$
Example 5
Convert $175.0\ \text{Speed of sound}$ to $\text{km/min}$.
$$\text{Speed}_{\text{km/min}} = 175.0 \cdot 20.4$$
$$\text{Speed}_{\text{km/min}} = 3570$$
$$\therefore \ 175.0\ \text{Speed of sound} = 3570 \ \text{km/min}$$
