PSLE The graph shows the height of a plant from March to July.
- What was the height of the plant in May?
- 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) = 25 cm
Height of the plant in April (4) = 34 cm
Height of the plant in May (5) =
39 cm Height of the plant in June (6) = 53 cm
Height of the plant in July (7) = 58 cm
Height of the plant in May (5) = 39 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) = 34 - 25 = 9 cm
Increase in height from April (4) to May (5) = 39 - 34 = 5 cm
Increase in height from May (5) to June (6) = 53 - 39 =
14 cm Increase in height from June (6) to July (7) = 58 - 53 = 5 cm
Period which the plant grew the most = May (5) to June (6)
Answer(s): (a) 39 cm; (b) 5 to 6
