Answer:
30 minutes
Explanation:
We know that you can type 50 words in 10 minutes, as along as being asked how long it'll take you to write 150 words.
W = Words
M = Minutes
Since we can read 50 words in 10 minutes, we can create our unit ratio.
We are looking to get 150 words, so multiply 50 by 3 and do the same for 10.
Therefore it takes 30 minutes to write 150 words.
