SPEED = DISTANCE/TIME
John and Caroline go out for a drive one day. The graph represents the distance they traveled over time.
During what part of their drive were they not moving?
From 0 to 0.75 hours
From 1.25 to 2.0 hours
From 0.75 to 1.25 hours
They are moving the entire time.
The graph represents the distance a car travels over time while on the highway. Which statement is true about the car's trip is accurate?
The car does not move more over time.
The car travels at a constant velocity.
The car's velocity increases constantly over time.
The car's velocity decreases constantly over time.
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.
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.
What do the four graphs have in common?
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.
Ben and Jerry went for a drive. They decided to stop for a snack and have some ice cream. How long did they stop at the store to eat ice cream?
1/2 hour
1 hour
1 1/4 hours
1 1/2 hours
The graph shows the speed of a car during a trip along the highway. What can you say, in general, about the speed of the car?
It is constant during the trip
It is moving at a slow rate of speed.
It is increasing throughout the trip
It varies at different times during the trip
During a race, four competitors of the same weight rode identical bicycles for 10 minutes. At 8 minutes, which bicycle was moving with the greatest velocity?
A
B
C
D
A car's position in relation to time is plotted on the graph. What can be said about the car during segment B?
The car travels for 80 seconds during segment B
The car has come to a stop and has zero velocity.
The car is traveling faster during segment B than in segment C
The car is traveling with a constant velocity due to he flat line of the graph.
