PSLE The graph shows the height of a plant from January to May.
- What was the height of the plant in May?
- 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) = 27 cm
Height of the plant in February (2) = 38 cm
Height of the plant in March (3) = 47 cm
Height of the plant in April (4) = 52 cm
Height of the plant in May (5) =
58 cm Height of the plant in May (5) = 58 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) = 38 - 27 =
11 cm Increase in height from February (2) to March (3) = 47 - 38 = 9 cm
Increase in height from March (3) to April (4) = 52 - 47 = 5 cm
Increase in height from April (4) to May (5) = 58 - 52 = 6 cm
Period which the plant grew the most = January (1) to February (2)
Answer(s): (a) 58 cm; (b) 1 to 2
