• 57. End of test 1996 Mathematics Paper B Q21a Jim draws a graph to show how high two rockets go during their flight. . Jim says, “ The graph shows that rocket A was more than 200 m above the ground for about 23 seconds.” Explain how the graph shows this.
• (c) Evidence of awareness that the time interval between the points where the 200m line cuts the graph for rocket A has been used, eg: 1
• · “He could have checked when the rocket went above 200m and when it went under 200m and worked out the time between.”
• · “Look how high it goes until it gets to 200m then look along the horizontal line until it drops below 200m.”
• An appropriate drawing on the graph, identifying the intersection of the 200m line with the curve is acceptable as part of explanation, eg, award mark for:
• · “Subtract the two dots” if dots are marked indicating correct intersections. Do not accept vague statements or ones which only repeat information, eg:
• · “You can draw the graph then draw the things then work it out.”
• · “Because on the graph the rocket is above 200m for 23 seconds.”
