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.
minutes

The distance from the Earth to the moon is 239,000 miles. The distance from the Earth to the moon is 385000 km. Given that light travels at 3.00 × 10⁸ m/s how many minutes does it take for light to travel to the moon?
How much time t (in seconds) does it take light to travel from the Moon to the Earth, a distance D = 384,000 km? Assume the speed of light is c = 3.00x108 m/s.
