Two machines, Y and Z, work at constant rates producing identical items. Machine Y produces 13 items in the same time Machine Z produces 14 items. If machine Y takes 28 minutes to produce a batch of items, how many minutes does it take for machine Z to produce the same number of items?	Pick one.
A) 26  B) 9  C) 9 1/2  D) 12  E) 13 1/2
