回答: 6 is right, you said how many planes need to provide gas for 1 由 wavelet 于 2006-09-29, 14:22:00:

• why it have to get 270+15? it can get fuel at 270 - wavelet (82 bytes) 2006-09-29, 15:20:08 (105159)
  • no plane can reach 270 and still supply - 4U4luC2 (53 bytes) 2006-09-29, 15:21:57 (105160)
    • You can however supply B with C's reminder at 300(3/1 tank) - 4U4luC2 (83 bytes) 2006-09-29, 15:27:17 (105166)
      • no, you don't need to, here is the sane procedure: - wavelet (131 bytes) 2006-09-29, 15:31:50 (105169)
        • right, I prviousely thought only two supplys - 4U4luC2 (75 bytes) 2006-09-29, 15:35:43 (105172)
    • if you can understand B in the first set of 3, then you can - wavelet (45 bytes) 2006-09-29, 15:26:38 (105164)
    • haha, the other set of 3 plane can fly from opposite direction - wavelet (24 bytes) 2006-09-29, 15:23:06 (105161)
      • A' give B' 1/3 gas at degree 300, then B' can give 1/3 gas - wavelet (30 bytes) 2006-09-29, 15:24:17 (105162)
        • thought we are talking about 5 planes :) (无内容) - 4U4luC2 (0 bytes) 2006-09-29, 15:30:16 (105168)
