The speed of light is about 3 x 108 meters per second. The Millennium Falcon is traveling from Earth to Mars
at the speed of light. The distance between the Earth and Mars fluctuates between 5.46 x 10¹0 meters and
4,01 x 10¹¹ meters.
If the day the Millennium Falcon makes the "Mars Run," the distance is 2.25 x 10¹¹ meters, how long will it
take them?
Note: distance = rate time, and time = distance/rate
Express your answer in scientific notation. Use for the multiplication.
seconds
Convert your answer to minutes. Include at least 3 decimal places in your answer, which can be expressed in
standard notation.
