Correct Answer

Explanation

The defining equation for velocity is

volume_mute

v = d / t

v = d * t

v = t / d

v = (t * d)²

Jogger Example

Suppose a jogger leaves her house and jogs north 300 meters to the streetlamp on the corner. She turns west, jogs another 300 meters, and gets the oak tree 2 minutes after leaving home

Which of the three distances given in the figure is the displacement d?
What is the jogger's average velocity?
What is the total distance (not displacement) travelled?
What is the average speed (not velocity) during the 2 minutes?

Please drag and drop the selected option in the right place or type it instead

350 meters/min

500 meters

700 meters

250 meters/min in a direction between north and west
