PSLE The graph shows the height of a plant from March to July.
- What was the height of the plant in April?
- 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 March (3) = 12 cm
Height of the plant in April (4) =
22 cm Height of the plant in May (5) = 31 cm
Height of the plant in June (6) = 36 cm
Height of the plant in July (7) = 39 cm
Height of the plant in April (4) = 22 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) = 22 - 12 = 10 cm
Increase in height from April (4) to May (5) = 31 - 22 = 9 cm
Increase in height from May (5) to June (6) = 36 - 31 = 5 cm
Increase in height from June (6) to July (7) = 39 - 36 =
3 cm Period which the plant grew the least = June (6) to July (7)
Answer(s): (a) 22 cm; (b) 6 to 7
