Question

What is the speed in miles per second of a beam of light traveling at 3.00×108m/s?

Answer 1

Answer: 186411.3 mi/s

Step-by-step explanation:

We have the speed of light in units of meters per second (
`(m)/(s)`):

`3(10)^(8) (m)/(s)`

And we need to express it in miles per second (
`(mi)/(s)`), knowing (
`1 m=0.000621371 miles`), then:

`3(10)^(8) (m)/(s) (0.000621371 miles)/(1 m)=186411.3 (mi)/(s)`
