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) = 25 cm
Height of the plant in February (2) = 35 cm
Height of the plant in March (3) =
43 cm Height of the plant in April (4) = 55 cm
Height of the plant in May (5) = 61 cm
Height of the plant in March (3) = 43 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) = 35 - 25 = 10 cm
Increase in height from February (2) to March (3) = 43 - 35 = 8 cm
Increase in height from March (3) to April (4) = 55 - 43 =
12 cm Increase in height from April (4) to May (5) = 61 - 55 = 6 cm
Period which the plant grew the most = March (3) to April (4)
Answer(s): (a) 43 cm; (b) 3 to 4
