Charlie began hiking from her campsite back to her car. Her campsite was located 9 miles from her car. She had walked for 1 hour
kkurt [141]

The graph which represents Charlies distance from her car at different times is indicated as attached. The schedule of her movement is also attached.  This type of graph is called Distance Time Graph.

<h3>What is a distance-time graph?</h3>

A distance-time graph can show the distance traveled while an item moves in a straight line.

The gradient of the line in a distance-time graph is equal to the object's speed. The item is travelling more quickly the steeper the line and the larger the gradient.

See the attached for Charlies Distance - Time movements visualized in a graph.

Mice21 [21]

Answer:

0.17

Step-by-step explanation:

The number of times there is free Breakfast at work = 25%

The number of times the coworker lies = 1/3

The number of times the coworker speaks truth = 2/3

How likely is it that there is free breakfast at work today:

For this to happen both conditions must be satisfied. There must be free breakfast at work AND the coworker has also spoken truth. Now in this condition we will use the AND rule of Probability where we will take the Product of both the probabilities.

Result = 0.25 x 0.67 = 0.17
