Answer:
64 books
Step-by-step explanation:
The first step is to find the number of books that will fit in the shelve per foot
= 40/5
= 8
Therefore the number of books that will fit perfectly in 8-foot shelf can be calculated as follows
= 8×8
= 64
Hence 64 books would fit in 8-foot shelf
64/7=9.14285714. It takes 9.14285714 or about 9 minutes to run a mile.
44/9=4.88888889. It takes 4.88888889 or about 5 dollars per hour.
