The approximate distance in miles between Los Angeles and a commercial jet flying from Boston to Los Angeles can be found using the function m=-475t+2,650 , where t is the number of hours the jet has been flying. Which number of hours and minutes is closest to the amount of time that the jet has been flying if the jet is 1,500 miles from Los Angeles

We need to solve this

 

1500 = -475t+2650   subtract 2650 from both sides

 

-1150  =  -475t        divide both sides by -475

 

t  ≈  2.42 hrs  =   2 hrs, 25 min
