PSLE The graph shows the height of a plant from February to June.
- 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 February (2) = 36 cm
Height of the plant in March (3) = 48 cm
Height of the plant in April (4) = 57 cm
Height of the plant in May (5) = 61 cm
Height of the plant in June (6) =
66 cm Height of the plant in June (6) = 66 cm
(b)
To find the greatest increase, look for the steepest increase in the line graph.
To prove:
Increase in height from February (2) to March (3) = 48 - 36 =
12 cm Increase in height from March (3) to April (4) = 57 - 48 = 9 cm
Increase in height from April (4) to May (5) = 61 - 57 = 4 cm
Increase in height from May (5) to June (6) = 66 - 61 = 5 cm
Period which the plant grew the most = February (2) to March (3)
Answer(s): (a) 66 cm; (b) 2 to 3
