Flying against the wind, an airplane travels 3750 kilometers in 5 hours. Flying with the wind, the same plane travels 6930 kilometers in 7 hours. What is the rate of the plane in still air, and what is the rate of the wind?

answer: the answer is ann

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

answer: 5
