PSLE The graph shows the height of a plant from February to June.
- What was the height of the plant in March?
- 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) = 36 cm
Height of the plant in March (3) =
41 cm Height of the plant in April (4) = 51 cm
Height of the plant in May (5) = 56 cm
Height of the plant in June (6) = 60 cm
Height of the plant in March (3) = 41 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) = 41 - 36 = 5 cm
Increase in height from March (3) to April (4) = 51 - 41 = 10 cm
Increase in height from April (4) to May (5) = 56 - 51 = 5 cm
Increase in height from May (5) to June (6) = 60 - 56 =
4 cm Period which the plant grew the least = May (5) to June (6)
Answer(s): (a) 41 cm; (b) 5 to 6
