Bean

Answer 2

Bean plant grew faster .

Explanation:

As given

Plants A birch tree grew 2.5 inches in five months.

i.e 2.5 inches = 5 months

Now calculate birch tree in one month .

`Birch\ tree\ grew\ in\ one\ month = (2.5)/(5)`

= 0.5 inches

As given

A bean plant grew 8 inches in 10 months.

i.e 8 inches = 10 months

Now calculate bean plant in one month .

`Bean\ plant\ grew\ in\ one\ month = (8)/(10)`

= 0.8 inches

As given

It rosebush grew 5 inches in eight months.

i.e 5 inches = 8 months

Now calculate rosebush in one month .

`Bean\ rosebush\ in\ one\ month = (5)/(8)`

= 0.63 inches (Approx)

Therefore Bean plant grew faster .
