Mia bicycles every day. Based on the graph, if Mia rides for 1.5 hours, how many miles does she bike? A. 5
B. 10
C. 15
D. 20

It is C because if you pinpoint 1.5 on the x axis and look at the y axis right above it, go to the right and you will see 15 so C is the answer.

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.
