Josh can walk 4 miles in 1 hour. How many miles can he walk in 3 hours

4 miles in one hour

8 miles in 2 hours

12 miles in 3 hours

multiply 4 by 3

because if he walks 4 miles every one hour he walks three times 4 miles in 1 hour.

hope this helps

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.
