Light travels at 300,000 km per second. mars is 56 million km away from earth. how many seconds does it take light to travel from mars to earth

It takes 186.67 second for the light to travel from Mars to earth.

Explanation:

Light: Light is a visible form of energy which is radiated outward from a source. Light travels in a straight line, and this phenomenon is called rectilinear propagation of light.

S = d/t Equation 1

making t the subject of the equation

t = d/S Equation 2

Where S = speed of light, d = distance between the earth and Mars, t = time

Given: d = 56000000 km, S = 300000 km per seconds.

Substituting these values into equation 2

t = 56000000/300000

t = 186.67 seconds.

Thus it takes 186.67 second for the light to travel from Mars to earth.

that would be b i just took the test : )
