rate=distance/time
2700/*=2025/y
2700/*=2025/*-1.5,
*diferent from 0,1.5
*=6hrs & y=4.5hrs
2700/*=2025/y
2700/*=2025/*-1.5,
*diferent from 0,1.5
*=6hrs & y=4.5hrs

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
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

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.
