During summer break, Jamie's family went camping in the mountains. There were no roads to their camp, 8 miles away, and it took them about 4.5 hours to reach the campsite on foot. Did Jamie's family stop to rest during the trip? How can you tell from the data?

Ответ:
The vertical axis represents the velocity of the object. This probably sounds obvious, but be forewarned—velocity graphs are notoriously difficult to interpret. People get so used to finding velocity by determining the slope—as would be done with a position graph—they forget that for velocity graphs the value of the vertical axis is giving the velocity.
Try sliding the dot horizontally on the example graph below to choose different times and see how the velocity changes.
