A Plane Begins Its Takeoff at 2:00 P

Multiple Choice

A plane begins its takeoff at 2:00 P.M.on a 2200-mile flight.After 12.5 hours, the plane arrives at its destination.Explain why there are at least two times during the flight when the
Speed of the plane is 100 miles per hour.

A) By the Mean Value Theorem, there is a time when the speed of the plane must equal the average speed of 303 mi/hr.The speed was 100 mi/hr when the plane was accelerating to
303 mi/hr and decelerating from 303 mi/hr.
B) By the Mean Value Theorem, there is a time when the speed of the plane must equal the average speed of 152 mi/hr.The speed was 100 mi/hr when the plane was accelerating to
152 mi/hr and decelerating from 152 mi/hr.
C) By the Mean Value Theorem, there is a time when the speed of the plane must equal the average speed of 88 mi/hr.The speed was 100 mi/hr when the plane was accelerating to 88
Mi/hr and decelerating from 88 mi/hr.
D) By the Mean Value Theorem, there is a time when the speed of the plane must equal the average speed of 117 mi/hr.The speed was 100 mi/hr when the plane was accelerating to
117 mi/hr and decelerating from 117 mi/hr.
E) By the Mean Value Theorem, there is a time when the speed of the plane must equal the average speed of 176 mi/hr.The speed was 100 mi/hr when the plane was accelerating to
176 mi/hr and decelerating from 176 mi/hr.
