Answer:
420 words per minute
Explanation:
This is because if christian types 240 words in 4 minutes, all we need to do is find how many words per minute christian types then multiply it by 7. So
240/4= 60,
Christian types 60 words per minute, so now we must multiply 60 and 7
60*7=420
So with that being said. Christian types 420 words in 7 minutes.
