Light travels at a rate of 3.0 x 108 meters per second. If the earth is 1.5 x 1011 meters away from the sun, how long does it take for light to travel from the sun to the earth?

Verified Answer :

I am assuming you mean 3.0 10^8 and 1.5 10^11.

time = distance/speed right. So, 
t = 500 s

Answer:

It takes 500 seconds

Step-by-step explanation:

Light travels at a rate of  3.0 × \(10^{8}\) meters per second.

Distance of earth from the sun is 1.5 × \(10^{11}\) meters.

We have to calculate the time it takes to reach the earth from sun

Since speed = \(\frac{Distance}{Time}\)

3.0 × \(10^{8}\) = \(\frac{1.5\times 10^{11}}{T}\)

T = \(\frac{1.5\times 10^{11}}{3\times 10^{8}}\)

  = 0.5 × \(10^{11}\) × \(10^{-8}\)

 = 0.5 × \(10^{11-8}\)

  = 0.5 × \(10^{3}\)

  = 500 seconds.

It takes 500 seconds for light to travel from the sun to the earth.
