Step-by-step explanation:

Given,Lucy can type 960 words in 20 minutes.

We want to find her typing speed in words per hour or 60 minutes. (We know,1 hour = 60 minutes).

By Unitary method,we can solve this problem.

But now question is what is the use of Unitary method ?

By some examples we can understand this concept.

Let cost of 5 apples is 50 rupees.

By Unitary method, cost of 1 pen is

$\frac{50}{5} \\ = 10 \: rupees$

Cost of 100 pens is $(100 \times 10) = 1000 \: rupees$

Here,in 20 minutes, Lucy can type 960 words.

By Unitary method,

In 1 minute,she can type $\frac{960}{20} = 48 \: words$

In 60 minutes,she can type $(48 \times 60) = 2880 \: words$
