We know the speed of light is a constant but speed is just the measure of distance over time. If blue light has a shorter wavelength than red but covers the same distance / time does this mean that blue light has actually made a longer journey than red light in order to arrive simultaneously?

I Imagine two roads that start and finish at the same point. A 5 mile straight road and a 10 mile bending road . A car will have to travel twice as fast on the winding road in order to finish at the same time
