John is driving to his office to attend a meeting. In the first 10 minutes, he covers a distance of 1 mile every minute. Then he stops at a local restaurant for 15 minutes to have breakfast. After that, he covers a distance of 0.5 miles every minute in the next 10 minutes to reach his office. Which graph models the piecewise function for the given situation?

The correct graph that models the piecewise function for the given situation is: (0, 0) (10, 10), (10, 10),(25, 10),(35, 15).

The correct graph that models the piecewise function for the given situation is:

In the first 10 minutes, John covers a distance of 1 mile every minute, so the graph should increase linearly from (0, 0) to (10, 10).

During the 15-minute break, John does not cover any additional distance, so the graph should remain at (10, 10) for the next 15 minutes.

In the next 10 minutes, John covers a distance of 0.5 miles every minute, so the graph should increase linearly from (25, 10) to (35, 15).

This piecewise function can be represented mathematically as:

f(t) = {

t, if 0 ≤ t ≤ 10

10, if 10 ≤ t ≤ 25

0.5t - 5, if 25 ≤ t ≤ 35

}
