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) = 19 cm
Height of the plant in April (4) =
27 cm Height of the plant in May (5) = 39 cm
Height of the plant in June (6) = 50 cm
Height of the plant in July (7) = 52 cm
Height of the plant in April (4) = 27 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) = 27 - 19 = 8 cm
Increase in height from April (4) to May (5) = 39 - 27 = 12 cm
Increase in height from May (5) to June (6) = 50 - 39 = 11 cm
Increase in height from June (6) to July (7) = 52 - 50 =
2 cm Period which the plant grew the least = June (6) to July (7)
Answer(s): (a) 27 cm; (b) 6 to 7
