    Any of the 5 beaches could be at first place. Keeping this in mind, we see that any 4 of the beaches left could be second place. So there are 5*4=20 combinations of first and second place. By the same argument, any of the 3 beaches left could be third place. In total, this gives us 60 different lists, since 60=5*4*3.
