total commercial flight times between two cities (for jets) can be modeled by the following linear equation: time =rate (miles) + fixed where time is in hours and miles is the distance between the two cities. the fixed time in hours represents the time for the takeoff and landing phases of the flight. this fixed time is relatively constant for flights under normal conditions. given a 3-hour flight of 1,250 miles and a 4.5-hour flight of 2,100 miles, determine the rate (to 5 dec. places) and fixed time (to whole minute) for this linear model.   rate =  ________hours/mile.        takeoff/landing time=_______min.
