Multiple Choice

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 4.5 hours to reach their campsite on foot. Did Jamie's family stop to rest during the trip? How can you tell from the data?

• No. They continued moving but their speed varied.

• Yes, after 1.5 hours, there is no change in position for 30 minutes.

• No. They continued moving, although they also slowed down continuously during the trip.

• Not really. They did stop, but that was only when they reached the campsites at distance equals 0.

Multiple Choice

Consider the 4 line graphs representing speed in meters/second, where each X-axis is labelled in seconds and each Y-axis labeled in meters.

• They all indicate a constant speed.

• They all indicate an increase in speed.

• All 4 graphs have nothing in common.

• They all represent the same speed in m/s.
