Question

The number of words Maria typed directly varied with with the amount of time she spent typing. If she typed 275 words in 5 minutes how long would it take her to type 1,100 words?

Answer 1

Answer: 20 minutes

Step-by-step explanation:

Given: The number of words Maria typed directly varied with with the amount of time she spent typing.

The formula of direct variation between two variables x and y is  given by :-

$\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}$

Let $y_2$ be the time taken by Maria to type 1,100 words, then

$\Rightarrow\ \dfrac{275}{5}=\dfrac{1100}{y_2}\\\\\Rightaarrow\ y_2=\dfrac{1100\times5}{275}=20\text{ minutes}$

Hence, she type 1,100 words in 20 minutes.

Answer 2

So for each minute she typed 55 words 
55(20) = 1100
so twenty minutes
