A plane begins its takeoff at 2:00 P.M. on a 1500-mile flight. After 5.5 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 200 miles per hour. Round your answers to the whole number. By the Mean Value Theorem, there is a time when the speed of the plane must equal the average speed of 136 mi/hr. The speed was 200 mi/hr when the plane was accelerating to 136 mi/hr and decelerating from 136 mi/hr. By the Mean Value Theorem, there is a time when the speed of the plane must equal the average speed of 273 mi/hr. The speed was 200 mi/hr when the plane was accelerating to 273 mi/hr and decelerating from 273 mi/hr. By the Mean Value Theorem, there is a time when the speed of the plane must equal the average speed of 400 mi/hr. The speed was C 200 mi/hr when the plane was accelerating to 400 mi/hr and decelerating from 400 mi/hr. By the Mean Value Theorem, there is a time when the speed of the plane must equal the average speed of 182 mi/hr. The speed was D 200 mi/hr when the plane was accelerating to 182 mi/hr and decelerating from 182 mi/hr. By the Mean Value Theorem, there is a time when the speed of the plane must equal the average speed of 200 mi/hr. The speed was 200 mi/hr when the plane was accelerating to 200 mi/hr and decelerating from 200 mi/hr
