The distance to the sun is 93,000,000 miles. The closest star is 270,000 miles times that. How long would it take to get a radio signal or light to that star?
Using the equation t=d/v, please explain how you came to your answer. Thanks!

The speed of light is 186282 miles per second. The total distance between the nearest star is:` `
`d=93000000 times 270000=2.511 times 10^13` miles
Since `t=d/v` we can substitute the values to get:
`approx 134800000` seconds
`approx 37400` hours
` ` `approx 1560` days
`approx 4.27` years
It would take approximately 4.27 years to get a radio signal (or light) to the nearest star.
