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) = 20 cm
Height of the plant in March (3) =
32 cm Height of the plant in April (4) = 37 cm
Height of the plant in May (5) = 49 cm
Height of the plant in June (6) = 50 cm
Height of the plant in March (3) = 32 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) = 32 - 20 = 12 cm
Increase in height from March (3) to April (4) = 37 - 32 = 5 cm
Increase in height from April (4) to May (5) = 49 - 37 = 12 cm
Increase in height from May (5) to June (6) = 50 - 49 =
1 cm Period which the plant grew the least = May (5) to June (6)
Answer(s): (a) 32 cm; (b) 5 to 6
