PSLE The graph shows the height of a plant from January to May.
- What was the height of the plant in March?
- 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 January (1) = 29 cm
Height of the plant in February (2) = 34 cm
Height of the plant in March (3) =
41 cm Height of the plant in April (4) = 56 cm
Height of the plant in May (5) = 65 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 January (1) to February (2) = 34 - 29 = 5 cm
Increase in height from February (2) to March (3) = 41 - 34 = 7 cm
Increase in height from March (3) to April (4) = 56 - 41 =
15 cm Increase in height from April (4) to May (5) = 65 - 56 = 9 cm
Period which the plant grew the most = March (3) to April (4)
Answer(s): (a) 41 cm; (b) 3 to 4
