Atrain left apex at 3 p. m. and traveled for 1 hour and 30 minutes. it stopped for fuel for 15 minutes, and then continued toward its destination for 2 hours and 10 minutes. what time did the train arrive at its destination?

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.
