100
Graph 1 $100 - At what time interval did the object stop?
WRITE: The object stopped between 6 minutes and 12 minutes because the graph is horizontal.
100
Graph 2 $100 - At what time interval did the object stop?
WRITE: The object stopped between 5 and 6 minutes and 10 and 12 minutes because the graph is horizontal.
100
Graph 3 $100 - At what time interval did the object stop?
WRITE: The object stopped between 20 and 40 seconds because the graph is horizontal.
100
Graph 4 $100 - At what time interval did the object stop?
WRITE: The object stopped between 1 and 2 hours and 4.75 and 6 hours because the graph is horizontal.
100
Graph 5 $100 - Which line shows an object that is stopped?
WRITE: Line C shows an object that is stopped because the line is horizontal.
200
Graph 1 $200 - During which time interval is the object moving the fastest?
WRITE: The object is moving the fastest between 0 and 6 minutes because the slope is the steepest.
200
Graph 2 $200 - During which time interval is the object moving the fastest?
WRITE: The object is moving the fastest between 6 and 8 minutes AND 12 and 20 minutes because the slope is the steepest.
200
Graph 3 $200 - During which time interval is the object moving the fastest?
WRITE: The object is moving the fastest between 40 and 60 seconds because the slope is the steepest.
200
Graph 4 $200 - During which time interval is the object moving the fastest?
WRITE: The object is moving the fastest between 6 and 7 hours because the slope is the steepest.
200
Graph 5 $200 - Which line shows the fastest object?
WRITE: The fastest object is shown by line A because it has the steepest slope.
300
Graph 1 $300 - During which time intervals is the object moving away from home?
WRITE: The object is moving away from home between 0 and 6 minutes and 12 and 20 minutes because the graph slopes up.
300
Graph 2 $300 - During which time intervals is the object moving toward home?
WRITE: The object is moving away from home between 6 and 8 minutes because the graph slopes down.
300
Graph 3 $300 - During which time intervals is the object moving away from home?
WRITE: The object is moving away from home between 0 and 20 seconds and 40 and 60 seconds because the graph slopes up.
300
Graph 4 $300 - During which time intervals is the object moving towards home?
WRITE: The object is moving away from home between 6 and 7 hours because the graph slopes down.
300
Graph 2 $300 - Which line shows an object moving away from home?
WRITE: Line D shows an object moving away from home because it is sloping down.
400
Graph 1 $400 - What is the average speed of the object between 0 and 6 minutes?
WRITE: The coordinate (6,3) tells me the object went 3 miles in 6 minutes. 3 miles ÷ 6 minutes = 0.5 miles/min
400
Graph 2 $400 - What is the average speed of the object between 0 and 5 minutes?
WRITE: The coordinate (5,2) tells me the object went 2 miles in 5 minutes. 2 miles ÷ 5 minutes = 0.4 miles/min
400
Graph 3 $400 - What is the average speed of the object between 0 and 20 seconds?
WRITE: The coordinate (20,10) tells me the object went 10 meters in 20 seconds. 10 meters ÷ 20 seconds = 0.5 m/s
400
Graph 4 $400 - What is the average speed of the object between 0 and 1 hour?
WRITE: The coordinate (1,10) tells me the object went 10 kilometers in 1 hour. 10 kilometers ÷ 1 hour = 10 km/hr
400
Graph 5 $400 - What is the average speed of the object represented by line B?
WRITE: The coordinate (10,9) tells me the object went 10 meters in 9 seconds. 10 meters ÷ 9 seconds = 1.11 m/s
500
Graph 1 $500 - What is the object's average speed between 12 and 20 minutes?
WRITE: Distance = 1 mile, time = 8 minutes, 1 mile ÷ 8 minutes = 0.125 mile/min
500
Graph 2 $500 - What is the object's average speed between 12 and 20 minutes?
WRITE: Distance = 4 miles, time = 8 minutes, 4 miles ÷ 8 minutes = 0.5 mile/min
500
Graph 3 $500 - What is the object's average speed between 60 and 100 seconds?
WRITE: Distance = 40 meters, time = 40 seconds, 40 meters ÷ 40 seconds = 1 m/s
500
Graph 4 $500 - What is the object's average speed between 2 and 5 hours?
WRITE: Distance = 10 kilometers (20 km - 10 km), time = 3 hours (5 hr - 2 hr), 10 kilometers ÷ 3 hours = 3.33 km/hr
500
Graph 5 $500 - What are we assuming about the speeds of these objects when we draw straight lines?
WRITE: We are assuming they are moving at a constant speed when we draw straight lines.
