The units are fine just the way they are in this problem, so we can skip this step. Once we get our answer in miles per sec, we will have to convert that to miles per hour. In order to make the red light appear green, we would have to travel at almost one-quarter of the speed of light, ,, miles per hour! There is a story about a man who tried to trick a judge into letting him out of a ticket by saying that he was going so fast that the Doppler Effect made the red light appear green to him.
