Final answer:
Emily should read a minimum of 32.5 minutes each day.
Step-by-step explanation:
To find the minimum number of minutes Emily should read each day, we first need to calculate the total number of minutes she has to divide among the 6 days (excluding the first day).
Since there are 4 hours in a week and 60 minutes in an hour, the total number of minutes she has is -
= 4 * 60
= 240 minutes.
Subtracting the 45 minutes it takes her to finish her first book, she is left with 195 minutes.
To divide this equally among the 6 days, we divide 195 by 6, which gives us approximately 32.5 minutes per day.
Therefore, Emily should read a minimum of 32.5 minutes each day.
