Oh, yeah! They are back! Leonardo, Donatello, Michelangelo, and Raphael – and they are as awesome as always! I am going to the new cinema located a few blocks away from my home to watch the new Teenage Mutant Ninja Turtles movie today, but I have a slight problem: I don’t know how much time it would take to get to the cinema.

My brother went to see the movie yesterday, so I asked him. But he likes riddles very much, and he didn’t want to give me a straight answer. He only said that he passed the bakery at Michigan Street, which is exactly one third of the way, at 4:20, and that he passed the big pond on Boston Street, which is exactly halfway to the cinema, at 4:23. He walked with a constant pace.

I’m confused. Can his riddle really help me calculate how long the walk to the cinema lasts? It can? Great! So, how long does the walk to the cinema last?
