PSLE The graph shows the height of a plant from July to November.
- What was the height of the plant in August?
- During which period did the plant grow the least? Give your answer in numbers. (Eg Jan to Feb = 1 to 2)
(a)
Height of the plant in July (7) = 21 cm
Height of the plant in August (8) =
29 cm Height of the plant in September (9) = 36 cm
Height of the plant in October (10) = 43 cm
Height of the plant in November (11) = 44 cm
Height of the plant in August (8) = 29 cm
(b)
To find the greatest increase, look for the steepest increase in the line graph.
To prove:
Increase in height from July (7) to August (8) = 29 - 21 = 8 cm
Increase in height from August (8) to September (9) = 36 - 29 = 7 cm
Increase in height from September (9) to October (10) = 43 - 36 = 7 cm
Increase in height from October (10) to November (11) = 44 - 43 =
1 cm Period which the plant grew the least = October (10) to November (11)
Answer(s): (a) 29 cm; (b) 10 to 11
