Click on screen to continue A girl leaves school at 3:00 and starts walking home. Her house is 2 km away. She gets home at 3:30. What was her average speed? Do you know her instantaneous speed at 3:15? Why or why not? Click on screen to continue

Click on screen to continue Her average speed is 2 km/.5h = 4km/h. It is impossible to know her instantaneous speed at 3:15 because she may not have been walking at a constant speed. Only her average speed can be found Click on screen to continue
