conversations.value: Jerry mows 8 acres of lawn each week. He mows ¾ of it with a riding mower that can cut 2 acres an hour. He mows the rest with a push mower that can cut 1 acre an hour. How long does Jerry mow each week?

conversations.value: Jerry mows 8 acres x ¾ = 6 acres with a riding mower.
  It will take him 6 acres / 2 each hour = 3 hours.
  Jerry mows 8 acres – 6 acres mowed with a riding mower = 2 acres with a push mower.
  It will take him 2 acres x 1 hour = 2 hours.
  It takes Jerry a total of 3 hours on the riding mower + 2 hours on the push mower = 5 hours.
