PSLE The graph shows the height of a plant from January to May.
- What was the height of the plant in February?
- 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 January (1) = 40 cm
Height of the plant in February (2) =
47 cm Height of the plant in March (3) = 55 cm
Height of the plant in April (4) = 67 cm
Height of the plant in May (5) = 70 cm
Height of the plant in February (2) = 47 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) = 47 - 40 = 7 cm
Increase in height from February (2) to March (3) = 55 - 47 = 8 cm
Increase in height from March (3) to April (4) = 67 - 55 = 12 cm
Increase in height from April (4) to May (5) = 70 - 67 =
3 cm Period which the plant grew the least = April (4) to May (5)
Answer(s): (a) 47 cm; (b) 4 to 5
