Answer:
She type <u>75 words</u> in 1 minute.
Step-by-step explanation:
Given:
Lolo typed 1,125 words in 15 minutes.
Let w represent the number of words typed each minute.
Now, to find the number of words she type in 1 minute if Lolo typed the same number of words each minute.
So, we solve it by using cross multiplication method:
<u><em>As 1125 words is equivalent to 15 minutes.</em></u>
<u><em>Thus, w number of words equivalent to 1 minutes</em></u>.
By cross multiplying we get:
⇒
<em>Dividing both sides by 15 we get:</em>
⇒
⇒
Therefore, she type 75 words in 1 minute.
