Question

Light travels 300,000,000 m/s

Answer 1

Answer:

1 x 10¹⁸cm

Explanation:

Given parameters:

Velocity of light  = 300,000,000cm/s

Unknown:

Distance in centimeters = ?

Solution:

To solve this problem,

  The velocity of light is 3 x 10⁸m/s

   Velocity   =  $\frac{distance }{time}$

Distance  = velocity x time  = 3 x 10⁸m/s  x 3.2 x 10⁷s

                                               = 9.6 x 10¹⁵m

             To cm;

         100cm  = 1m

 Distance  =  9.6 x 10¹⁵ x 10²   = 9.6 x 10¹⁷cm = 1 x 10¹⁸cm
