Question

If Mars is 1.5x10⁸ km from Earth, how long does it take radio signals from the Curiosity rover to reach us? (the speed of light is about 3x10⁵ km/sec)

Definition Definition Rate at which light travels, measured in a vacuum. The speed of light is a universal physical constant used in many areas of physics, most commonly denoted by the letter c . The value of the speed of light c = 299,792,458 m/s, but for most of the calculations, the value of the speed of light is approximated as c = 3 x 10 8 m/s.
