    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: (1/2)(h)=t-10 h=2(t-10) This is the equation Now substituting into the equation the known information you get: h=2(13-10) h=(2)(3) h=6 hours The average speed is calculated as follows: 3300 miles/6 hours=550 miles per hour
