Q1:

The graph shown displays the changes in the distance moved by an object that travels at a constant speed for a time of 8 seconds. The distance axis of the graph has a resolution of 4 meters. Only the values of distance that are integer multiples of 4 are recorded in the table shown.

Time in Seconds	0	1	2	3	4	5	6	7	8
Distance in Meters	0				20				40

What distance value should be entered in the table for a time value of 2 seconds?

What distance value should be entered in the table for a time value of 3 seconds?

What distance value should be entered in the table for a time value of 6 seconds?

Q2:

The changes in the speeds of three objects during the same time interval are shown in the graph.

Which object has the greatest initial speed?

Which object has the greatest final speed?

Which object has the greatest average speed?

Which object was not moving?

Q3:

The graph shows the changes in the distance walked by a dog in a time interval of 8 seconds.

At what time did the dog change its speed?

Was the dog’s speed higher or lower before the point when its speed changed?

What is the difference between the speed of the dog before and after it changed speed?
