Answer 2

Calculating the Time for a Radio Signal to Travel from Earth to the Moon

To calculate the time it takes for a radio signal to travel from the surface of the Earth to the Moon, we can use the formula:

Time = Distance / Speed

Where: - Distance is the distance from the Earth to the Moon, which is 384,400 km. - Speed is the speed of light, which is approximately 299,792 kilometers per second (km/s).

Calculation

Using the given distance of 384,400 km and the speed of light of 299,792 km/s, we can calculate the time it takes for a radio signal to travel from the Earth to the Moon.

Time = Distance / Speed Time = 384,400 km / 299,792 km/s Time ≈ 1.28 seconds

Therefore, the radio signal, sent from the surface of the Earth to the Moon, will be received by a radio transmission station on Earth in approximately 1.28 seconds.
