The average length of three tapes is 6800 feet. None of the tapes is less than 6400 feet. What is the greatest possible length of one of the other tapes?

1. x+y+z
   —– = 6800
   3
   x>=6400
   6400 + y + z = 20400
   y + z = 14000
   to get the greatest of y and z, lets assume y = 6400
   so, z = 7600
   so ANS is 7600
