.
The student writes 24 words/6 minutes=4 words per minute
The teacher writes 18 words/3 minutes=6 words per minute
.
The student writes 2 minutes x 4 words per minute = 8 words
before the teacher starts to help, leaving 80 words.
.
Together they write 4 words/min + 6 words/min = 10 words/min
.
To write the remaining 80 words:
80 words/10 words per minute=8 minutes.
.
ANSWER: It takes 8 minutes after the teacher begins to help to finish the 88 words.
