If Mars is about 1.5 AU from the Sun why does it take light or radio waves 8 minutes to get from the Sun to the Earth but it takes between 10 and 20 minutes to get from Earth to Mars?

Earth's average distance from the sun = 1 AU = 93 million miles
Distance in terms of light-speed = (93,000,000) / (186,282) = 499 sec = 8min 19sec
Mars' average distance from the sun = 1.52 AU = 141.4 million miles
Distance in terms of light-speed = (141,400,000 / 186,282) = 759 sec = 12min 39sec
What's the problem ?

How long does it take radio waves to travel from earth to Jupiter?
The distance between Earth and Jupiter can be anywhere between roughly 391 and 577 million miles, depending on where each of them is in its orbit. The corresponding transit times for radio (or light, heat, etc.) are: 390.8 million miles . . . 35 minutes 576.8 million miles . . . 51.6 minutes
How long does it take radio waves to reach mars?
Radio waves travel at the speed of light. When the Spirit rover landed on Mars, signals were able to be sent from the Earth to Mars in 9 minutes 30 seconds. Unfortunately, the rover became stuck and hasn't sent a signal to Earth since March 22, 2010.
How many minutes does it take for a radio message to reach earth from Saturn is 7.9 times 10 to eight?
The closest Saturn can be to earth is at the moment when both planets are lined upon the same side of the sun. Then, the distance is 797.8 million miles. Light and radiotake 71.4 minutes to cover that distance.The farthest Saturn can be from earth is at the moment when both planets are lined upon opposite sides of the sun. Then, the distance is 983.8 million miles. Light and radiotake 88 minutes to cover that distance.
Why do you use only two types of telescopes here on earth optical or radio telescopes?
Radiation other than light and radio waves hardly penetrates Earth's atmosphere.
How long does it take a radio wave to travel to Saturn from earth?
Using the formula speed = distance/time and that Saturn from earth is 821,190,000 miles and the speed of light 186,000miles per second. Then rearrange the formula for time we find the answer is 4415 seconds or 73.58 minutes or 1.226 hours

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 formula is used to figure the time it takes a radio signal to travel from Mars to Earth?
Radio waves, like all other waveforms in the electromagnetic spectrum travel at what is known as the speed of light. i.e. 3x10 to the power 8 metres per second (300,000,000) but the distance between the earth and mars varies enormously depending on their relative positions in their orbits around the sun. Anything from approx 35 million miles at it's nearest to about 340 million miles or thereabouts at it's furthest. So roughly 3 minutes minimum to about 30 minutes maximum.
How long does it take to transmit a picture from a spacecraft on mars to earth?
*The speed of light in TV signals is 186,282 miles/second. 130,000,000 miles(the distance between Mars and Earth)_______________________________________________ = 697.87 seconds 186, 282 miles/ second (the speed of light) (697.87seconds is about 698 seconds, which is about 12 minutes (11.633333333333333 minutes).
What is the difference between a radio telescope and a light telescope?
radio telescope detects radio waves and a light telescope views light waves.
Speed of radio communication from earth to space?
Radio signals travel at the speed of light and all other forms of electromagnetic radiation. That means roughly 2.5 seconds to the moon and back, 8.7 minutes to Mars and back when it's closest to earth, 17 minutes to the sun and back, 9 years to the nearest star and back, etc.
What is the diameter of the earth in light minutes?
The Earth's diameter is roughly 8,000 miles. If the light is traveling in vacuum, then8,000 miles is roughly 0.043 of one light-second, or roughly 0.00072 of a light-minute.
What happen when they behind the moon?
They lose radio contact with the Earth for a few minutes.
Why did it take 7 minutes for the radio signal to travel from the Curiosity back to earth?
Radio waves travel "at the speed of light" which, though very fast, is still a finite speed. Mars is far away so it takes 7 minutes for the radio waves to travel the distance from Curiosity to the Mars orbiter that then relays radio communications to Earth. How much delay in the electronics of the relay station in the orbiter and the electronics on Earth I cannot be certain, but certainly a measurable amount though probably less than a few seconds.
How long for x-rays from sun to dissipate on earth?
X-rays are one form of electromagnetic radiation, like light and radio. They travel at the speed of light, 186,000 miles per second. The Earth is about 93,000,000 miles from the Sun, so it takes about 8 minutes 20 seconds to arrive on Earth.

What happens when they go behind the moon?
They lose radio contact with the Earth for a few minutes.
