15 minutes since the combined speed of both cyclists is 20 mph away from one another. Takes 1/4 of an hour to travel 1/4 of that distance.

How long would it take radio signals to travel from Earth to Venus and back if Venus were at its farthest distance from Earth?

Practical Answer If the distance between Earth and Venus is to be maximum, then the two planets would have to be on opposite sides of the Sun. There would be no way to send radio waves to Venus in this situation as the waves cannot travel through the Sun. So, in reality, this question has no answer.Theoretical Answer For the sake of curiosity, lets assume the waves travel through the Sun in a straight line.: Earth's average distance from the sun = 93,000,000 miles Venus' average distance from the sun = 67,200,000 miles Max separation (opposite directions from the sun) = 160,200,000 miles Speed of radio (light) = 186,282 mi/sec Time for a radio or radar return = 2 x (160,200,000 / 186,282) = 1,720 seconds = 28-2/3 minutes(rounded)
