a family took 2 hours to drive from city a to city b at a speed of 55 miles per hour. On the return trip, due to a snowstorm, the family took 3 hours to travel back to City a. How many miles did the family travel in all? What was teh average speed for the entire trip?

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.

sorry i really don't know what tiles and steps you are referring to
