Radio waves travel at the speed of light 3.00x10^8m/s. If you were to broadcast a question to the Mars rover spirit on Mars which averages 225,000,000 Miles from earth. What is the minimum time that you would have to wait to receive a reply?

How many hours Dimensional Analysis

The Voyager 2 mission to the outer planets of the solar system transmitted spectacular photographs of Neptune to Earth by radio. Radio waves, like light waves, travel at 3.00x10^8 m/s. If Neptune was 2.75 billion miles from Earth during these transmissions, how many Hours were required for radio signals to reach Earth from Neptune? (Note: 1mile = 5280 ft). Please show all work through Dimensional Analysis

The distance from Earth to the Moon is approximately 240,000 mi. (a) What is this distance in meters? (b) The peregrine falcon has been measured as traveling up to 350 km/hr in a dive. If this falcon could fly to the Moon at this speed, how many seconds would it take? (c) The speed of light is 3.00 10⁸ m/s. How long does it take for light to travel from Earth to the Moon and back again? (d) Earth travels around the Sun at an average speed of 29.783 km/s. Convert this speed to miles per hour.

In order to travel to the Moon, it would take:

c) In this case, the distance is doubled since the light should go to the Moon and come back.
