I apologize for the incorrect response. Let's go through the calculations again.

Miss Chen bought a box of 20 assorted books for $40. To find the cost per book, we need to divide the total cost by the number of books.

$40 / 20 books = $2.00/book

So, the correct answer is $2.00/book.

To convert the ratio into a unit rate, we divide the time (in minutes) by the distance (in miles).

15 minutes / 3 miles = 5 minutes/mile

So, the correct answer is 5 minutes/mile.

Apologies for the incorrect response. Let's re-evaluate the situation.

Liam took 15 minutes to ride his bike for three miles. To find the unit rate, we need to determine how long it took him to travel one mile. We can do this by dividing the total time by the total distance.

15 minutes / 3 miles = 5 minutes/mile

Therefore, the correct answer is 5 minutes/mile.
