Final answer:
By dividing the time taken to read 1/11 of the book (two-fifths of an hour) by 1/11, we find that it will take Jamaal 4 and two-fifths hours to read the entire book.
Step-by-step explanation:
The student's question is about determining the total time it will take for Jamaal to read an entire book based on the rate at which he has been reading. Since Jamaal read 1/11 of a book in two-fifths of an hour, we can calculate the time taken to read the whole book by dividing the time taken to read the portion of the book (i.e. two-fifths of an hour) by the fraction of the book that was read (i.e. 1/11).
The calculation would be as follows:
(2/5 hour) / (1/11) = (2/5) * (11/1) hours = 22/5 hours = 4 and two-fifths hours.
This means it would take Jamaal 4 and two-fifths hours to read the entire book at his current reading rate.
