The speed of light in MPH is 6.71×10⁸ MPH.
The speed of light is v=3×10⁸ m/s
To convert a physical quantity from meter per second to miles per hour, we need to multiply the quantity by a value of 2.237.
Thus the speed of light in miles per hour is given by,
[tex]\begin{gathered} v=3\times10^8\times2.237 \\ =6.71\times10^8\text{ miles/hr} \end{gathered}[/tex]Thus the speed of light in miles per hour is 6.71×10⁸ mph
