Answer: 186411.3 mi/s
Explanation:
We have the speed of light in units of meters per second ([tex]\frac{m}{s}[/tex]):
[tex]3(10)^{8} \frac{m}{s}[/tex]
And we need to express it in miles per second ([tex]\frac{mi}{s}[/tex]), knowing ([tex]1 m=0.000621371 miles[/tex]), then:
[tex]3(10)^{8} \frac{m}{s} \frac{0.000621371 miles}{1 m}=186411.3 \frac{mi}{s}[/tex]
