It will take 40 minutes for her to plant all 70 flowers that she has. By using proportions, we can find this value.

To calculate a word problem using proportions is as follows:

Consider the details of the word problem in proportions as

a : b = c : d

Here, a: b is the ratio of an event, and c : d is the ratio of another event.

Then, to find the value of c we need to reframe the above proportion into

c = ad/b

This is also said to be a cross formula in terms of word problems.

It is given that, Caroline is planting flowers in her garden.

She plants her first 7 flowers in 4 minutes.

After 12 minutes, she planted 21 different flowers.

Then, she takes x minutes for planting 70 flowers.

(Since the rate of planting is the same)

So, we can write

70 : 21 = x : 12

⇒ x = (70× 12)/21 = 40 minutes

Therefore, Caroline takes 40 minutes for planting all 70 flowers.
