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

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

Answer 2

Answer: 20 minutes

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 :-

`(x_1)/(y_1)=(x_2)/(y_2)`

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

`\Rightarrow\ (275)/(5)=(1100)/(y_2)\\\\\Rightaarrow\ y_2=(1100*5)/(275)=20\text{ minutes}`

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