    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.
