  1. rate=distance/time

    2700/*=2025/y
    2700/*=2025/*-1.5,
    *diferent from 0,1.5

    *=6hrs & y=4.5hrs

  2. Let their rate be x mph
    time for first = 2700/x
    time for second = 2025/x

    2700/x - 2025/x = 1.5
    times x
    2700 - 2025 = 1.5x
    x = 450
    so the first flew for 2700/450 hrs or 6 hrs
    a nd the 2nd flew for 2025/450 or 4.5 hrs

    notice the difference is 1.5 hrs

  6. yup, that's what it means.
    So what is " *diferent from 0,1.5 " and " 2700/*=2025/*-1.5, " ???

    That's what I was objecting to.
