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) = 38 cm
Height of the plant in August (8) =
50 cm Height of the plant in September (9) = 56 cm
Height of the plant in October (10) = 61 cm
Height of the plant in November (11) = 65 cm
Height of the plant in August (8) = 50 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) = 50 - 38 = 12 cm
Increase in height from August (8) to September (9) = 56 - 50 = 6 cm
Increase in height from September (9) to October (10) = 61 - 56 = 5 cm
Increase in height from October (10) to November (11) = 65 - 61 =
4 cm Period which the plant grew the least = October (10) to November (11)
Answer(s): (a) 50 cm; (b) 10 to 11
