Distance = 3.03 x 109 km
Speed of radio = 3 x 108 m/s = 3 x 105 km/s
Time = (distance)/(speed) = (3.03 x 109)/(3 x 105) = 1.01 x 104 seconds = 2hrs48.3min (rounded)

The Voyager 1 spacecraft is currently about 18.5 billion km from the Earth. How long does it take in seconds for a radio signal to get from Voyager 1 to Earth?
That distance you gave is nearly 200 astronomical units so if that is right the time would be 8 minutes times 200, which is 26½ hours.
The space craft that flew by and photographed the four gas giants in the 1970's?
That was the Voyager I and II spacecraft. Voyager I is 10 billion miles away from the sun (the Earth is only ~93 million miles from the sun and Pluto is 3.67 billion miles). A radio signal from Voyager takes ~15 hours to reach Earth.
What is the difference between radio horizon and optical horizon?
radio signal bents around the curvature of earth and hence travel longer distance than the line of sight signal. At ultra high frequencies signal follows the line of sight path and hence maximum communication distance is limited due to curvature of earth for given height of transmitting and receiving antenna
What is the time it takes for a signal to travel?
Communication with spacecraft is by means of radio. Signals travel at the speed of light. At that speed, signal travel one-way to or from the moon takes about 1 and 1/4 seconds. For Mars, depending on where the earth and Mars are in their orbits, radio communication one-way can take up to 22 minutes.
How long does it take the reflected ray of light from the full moon to get to earths surface?
1.28 seconds at the moon's average distance from earth ... same as for a radio signal.
How long does it take a radio signal from the Voyager spacecraft to reach Earth if the distance between Voyager and Earth is 4.16 109 km?
The speed of light is about 300,000 km/sec. Just divide the distance by the speed of light. The answer will be in seconds; divide by 60 to get minutes, by 3600 to get hours, or by 86400 to get days.

What is the use of an amplifier?
Increase the incoming signal between every even distance

1.A certain spacecraft is 3.3 AU (Astronomical Units) from Earth. How long in seconds does it take for a signal to reach the Earth after it is transmitted from the spacecraft Hint An AU is about 149.9?
One AU, the distance from the Earth to the Sun, is 500 light-seconds. A signal to a spacecraft at a distance of 3.3 AU would take 500 x 3.3 = 1,650 seconds, or 27.5 minutes.
Why would turn signal lights not work on 2000 Plymouth voyager?
The Turn Signal Switch is bad in the column and needs to be replaced.
What is the distance between signal towers on The Great Wall of China?
Interestingly, the distance varies from a hundred yards (or less ) to a quarter of a mile (or more!).
What does the Code 22 on a 1995 Plymouth Voyager mean?
22- Coolant sensor signal out of range22- Coolant sensor signal out of range
What cause echo on mobile phones?
Echo can be caused by Atmospheric, magnetic between 2 signal points, depending on location & distance of signal points & caller
What happens to the distance between the crests when the amplitude is increased?
Nothing happens. Distance between crests is a measure of frequency; amplitude is a measure of the strength, the height of the wave, or auditory volume of the signal.
What are the advantages of tree network?
Central hub (repeater) increases the distance a signal can travel between devices.
