Step-by-step explanation:
Let the water surface be 0.
He starts at 15 and gets to the water surface of 0 so he travels 15 meters.
He then goes 5 meters below the surface.
15 + 5 = 20 total meters.
factors of 18: 1,2,3,6,9
factors of 30: 1,2,3,5,6, 10, etc.
The greatest number of book for each shelf is 6.
18/6=3 shelves
30/6 =5 shelves
5+3= 8 shelves
There will be 8 shelves for each book.
