Hi there!
Answer:
It will take Hannah 4 minutes to type a 200 words paper.
Explanation:
In order to answer your question, you'll need to use the cross product method:
50 words → 1 minute
200 words → x minutes
(1 × 200) ÷ 50 = x minutes
200 ÷ 50 = x minutes
4 = x minutes
There you go! I really hope this helped, if there's anything just let me know! :)
