PSLE The graph shows the height of a plant from June to October.
- What was the height of the plant in August?
- During which period did the plant grow the most? Give your answer in numbers. (Eg Jan to Feb = 1 to 2)
(a)
Height of the plant in June (6) = 37 cm
Height of the plant in July (7) = 41 cm
Height of the plant in August (8) =
47 cm Height of the plant in September (9) = 62 cm
Height of the plant in October (10) = 71 cm
Height of the plant in August (8) = 47 cm
(b)
To find the greatest increase, look for the steepest increase in the line graph.
To prove:
Increase in height from June (6) to July (7) = 41 - 37 = 4 cm
Increase in height from July (7) to August (8) = 47 - 41 = 6 cm
Increase in height from August (8) to September (9) = 62 - 47 =
15 cm Increase in height from September (9) to October (10) = 71 - 62 = 9 cm
Period which the plant grew the most = August (8) to September (9)
Answer(s): (a) 47 cm; (b) 8 to 9
