WILL GIVE BRAINLIEST! Two small planes start from the same point and fly in opposite directions. The first plane is flying 40 mph slower than the second plane. In 3 h, the planes are 750 mi apart. Find the rate of each plane.
slower plane
mph
faster plane
mph

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile

step-by-step explanation:

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.
