Stan likes music, and likes oldies the best. In his collection of music he has a cassette tape of “The Cassettes 20 Greatest Hits”. The amazing thing about the 20 Greatest Hits, is that each hit is exactly 3 minutes long. This fits perfectly on a 60-minute tape.
Songs 1 – 10 are on Side A, while 11 – 20 are on Side B. When listening to the tape, Stan does one strange thing. He listens to the first 5 songs on side A, then flips it to the other side. He then listens to Side B from that point until the tape ends. How many songs does Stan hear?
The tape is wrapped around two spools that have identical diameters of 1 cm.
The spool that is receiving the tape rotates at a constant speed.
The tape, when located all on one spool, measures 5 cm in diameter.
i think that you dont have to know all of the things w/ the dots in front. since the tape plays in the opposite direction when flipped, and each song is the same length, side B will also play 5 songs.
