PSLE The graph shows the height of a plant from April to August.
- What was the height of the plant in June?
- 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 April (4) = 33 cm
Height of the plant in May (5) = 42 cm
Height of the plant in June (6) =
50 cm Height of the plant in July (7) = 63 cm
Height of the plant in August (8) = 67 cm
Height of the plant in June (6) = 50 cm
(b)
To find the greatest increase, look for the steepest increase in the line graph.
To prove:
Increase in height from April (4) to May (5) = 42 - 33 = 9 cm
Increase in height from May (5) to June (6) = 50 - 42 = 8 cm
Increase in height from June (6) to July (7) = 63 - 50 =
13 cm Increase in height from July (7) to August (8) = 67 - 63 = 4 cm
Period which the plant grew the most = June (6) to July (7)
Answer(s): (a) 50 cm; (b) 6 to 7
