Greetings to all ...

My wife and I got into a discussion last nite after looking at Mars
through the telescope. A question arised and we were wondering
if someone could answer it ...

If a radio signal travels at the speed of light (186,200 miles per
second), then how long would it take it to get to Mars - from Earth?

36,000,000 miles is a very long way for a radio signal to travel


Thanks in advance!
