  1. since the average of the 5 flight is 2 : 28
    the total time was 5(2:28)
    = 10:140
    = 12:20

    first 4 flights:
    2 : 10
    3 : 20
    1 : 15
    2 : 40
    ------
    8 : 85 = 9 : 25

    last leg = 12:20 - 9:25
    = 2 : 55

    Too bad the world can't can convert to "metric time"
    It would make things soooo much easier.

  3. Convert hours to minutes. Add all 4 known flights to get 565 minutes. Solve for "x".....565+x divided by 5 equals 148 minutes...148 x 5 = 740. 740-565=175 minutes...eqyals 2 hours 45 minutes (convert back to gours/minutes).
