Answer:

671080887.619 miles/hour

Step-by-step explanation:

Given : Speed of light = 300,000 kilometers per second

To Find: Convert the speed to miles per hour

Solution :

1 kilometer = 0.621371 miles

3600 second = 1 hour

So, 1 second = $\frac{1}{3600}$

So, speed of light in miles per hour:

= $\frac{300000\times 0.62137119224}{\frac{1}{3600}}$

= $\frac{300000\times 0.62137119224\times3600 }$

= $671080887.619$

Thus the speed of light is 671080887.619 miles/hour
