Answer: 32.5 minutes a day
Explanation:
First, we will see how much reading she still has to do. We will subtract what she has read from the total reading time.
4 hours = 240 minutes, 240 minutes - 45 minutes = 195 minutes
Next, we will divide this number by the number of days left.
195 minutes / 6 days = 32.5 minutes a day
