The distance between Earth and Pluto varies as the two planets move around their orbits. When they are closest, they are about 29 A.U. apart; at most, the distance is about 51 A.U. Since light travels about 300,000 kilometers each second, it would take light anywhere between 8 hours and 14 hours to make the round-trip journey to Pluto from Earth.
Radio signals travel at the same speed as light. If you were using radio signals to control a robot on Pluto, you would have to be very patient. If you sent your robot a command to move, the command would arrive at least 4 hours later. Then, if your robot took a picture and sent it back to Earth, it would take at least 4 more hours before you could see that picture!
AU, which stands for "astronomical unit", is a unit for measuring distance. One AU is the average distance from the Sun's center to the Earth's center. It is equal to 149,597,871 km (92,955,807 miles).

Earth is 1 Astronomical Unit (AU, or about 93 million miles) from the sun. Pluto is about 38 AU from the sun.
At minimum distance, about 37 AU, or 3.4 billion miles.

The closest it comes is 2.66 billion miles, and the farthest is about 4.67 billion miles.
That's just over 4 light hours at the closest.

Well put it this way, you could be travelling at light speed for a day with your kid in the back. And after a day the kid asks "Are we there yet?" Most likely the Answer is no :)
