Answer:
2/5 of their novel
Explanation:
20 minutes is 1/3 of an hour, so 20*3 gets you an hour. Now we can do 2/15*3 because that's how many "batches" of 20 minutes there are. 2*3=6 so it would be 6/15, this would be you answer. But, we can simplify this fraction by dividing the numerator and denominator by 3. This gets you 2/5.
