It's your first day on the job at Expii Airport. Po is arriving in his private jet, P314. His plane is flying a distance of 6,5806{,}580 miles and left at 2:002{:}00 am.

Suddenly three other planes request permission to land.

  • Plane 1 is traveling 3,2903{,}290 miles at the same speed of Po's plane. It will complete its trip 77 hours less than the time it takes Po's plane to complete its trip but it left at 9:009{:}00 am.
  • Plane 2 is traveling 26002600 miles but 180180 miles per hour faster than Po's plane. It will complete its trip 33 hours less than the time it takes Plane 1 to complete its trip but it left at 12:00 pm.
  • Plane 3 is traveling 34\frac34 the distance of Po's plane but is going 517517 miles per hour faster. It will complete its trip 1 hour longer than the time it takes Plane 2 to complete its trip but it left at 10:0010{:}00 am.

During the time at which Po's plane lands, there isn't any room left on the runway for another plane. Which of the three planes can you allow to land?
