PSLE The graph shows the height of a plant from February to June.
- What was the height of the plant in May?
- 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 February (2) = 27 cm
Height of the plant in March (3) = 36 cm
Height of the plant in April (4) = 38 cm
Height of the plant in May (5) =
50 cm Height of the plant in June (6) = 58 cm
Height of the plant in May (5) = 50 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) = 36 - 27 = 9 cm
Increase in height from March (3) to April (4) = 38 - 36 =
2 cm Increase in height from April (4) to May (5) = 50 - 38 = 12 cm
Increase in height from May (5) to June (6) = 58 - 50 = 8 cm
Period which the plant grew the least = March (3) to April (4)
Answer(s): (a) 50 cm; (b) 3 to 4
