PSLE The graph shows the height of a plant from March to July.
- What was the height of the plant in July?
- 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 March (3) = 12 cm
Height of the plant in April (4) = 23 cm
Height of the plant in May (5) = 32 cm
Height of the plant in June (6) = 41 cm
Height of the plant in July (7) =
51 cm Height of the plant in July (7) = 51 cm
(b)
To find the greatest increase, look for the steepest increase in the line graph.
To prove:
Increase in height from March (3) to April (4) = 23 - 12 =
11 cm Increase in height from April (4) to May (5) = 32 - 23 = 9 cm
Increase in height from May (5) to June (6) = 41 - 32 = 9 cm
Increase in height from June (6) to July (7) = 51 - 41 = 10 cm
Period which the plant grew the most = March (3) to April (4)
Answer(s): (a) 51 cm; (b) 3 to 4
