Question

The height of a particular tree is increasing at the rate of 10cm per month. What would be the height of the tree after 5 years if its present height is 10 m? (Growth of tree is uniform).

Answer 1

Present Height = 10m

If the rate increases 10 cm per month then:

1 month = 10 cm

12 months ( 1 year) = 10x12=120 cm

5 years = 120 x 5 = 600 cm

Convert cm into m

1 cm = 0.01 m

600 cm = 0.01 x 600 = 6 m

present height = 10 m

Add 5 years = 10 m + 6 m = 16 m

The answer is 16 m
