The plane flew at a speed of 460 miles per hour for the first 75 minutes of the flight and at a speed of 439 miles per hour for the remainder of the flight. To the nearest minute, for how many minutes did the plane fly at a speed of 439 miles per hour?
The correct answer is: 90
75 minutes = 
hour
So, can assume that lost minutes at a speed of 439 miles per hour
So that
x = 89.9
