on each flight an airplane is filled with 10 quarts of oil. the airplane adds an additional 1/2qt of oil for each planned hour of flying. write a equation that can be used to determine the planned flying time (h) in hours for a airplane filled with 13qts of oil equation:
that airplane flies 3300 miles. what is the average speed in miles per hour of the airplane?

Let h=planned flying time in hours
Let t=total quarts of oil filled in the plane
Therefore, the equation can be set up as follows:
h=2(t-10) This is the equation
Now substituting into the equation the known information you get:
The average speed is calculated as follows:
3300 miles/6 hours=550 miles per hour
