Answer:
4.25 minutes.
Explanation:
If she types 42 in 1/2 a minute that means she can type 84 in a whole minute. So, you divide how many words she has (357) by how many she can type per minute (84) and you get how long it will take her (4.25 minutes)
Hope this helps!
30 seconds = 42 words
60 seconds = 82 words
