# Jenny can type 1,200 words in 30 minutes. How long will it take her to type a 3,000-word essay?

Mar 24, 2018

1 hour, 15 minutes

#### Explanation:

Let's put this into a proportion
I'm going to use $x$ to represent the unknown time it takes to type a 3000 word essay

$\frac{1200}{30} = \frac{3000}{x} \rightarrow$ 1200 words in 30 minutes equals 3000 words in x minutes (The rate of her typing is the same)

$40 = \frac{3000}{x}$

$40 x = 3000$

$x = 75 \rightarrow$ It'll take 75 minutes (1 hour 15 minutes) to type a 3000 word essay.
