Question

Enter the warehouse and go forward six feet, making sure to move the half dozen

boxes of bolts out of the way.
Travel forward another nine feet. Here, clear away all 10 crates of ball bearings that
are in the way
Walk the remaining fifteen feet to the 3 barrels by the far wall. You will need to move
two of those barrels.
After finishing your work, turn around and come straight back the way you walked in.
What is the total number of items that must be cleared away to make space in the
warehouse?

Answer 1

Total of 18 items must be cleared to make the space in the warehouse.

Step-by-step explanation:

Assuming that we are at Point Zero and has removed none of the boxes so far. We would keep a tab on our movement following the cartesian coordinates and increase the box count as we displace any of them.

Step 1- Moving forward 6 feet and removing half a dozen boxed. Hence the box count =6

Step 2- Moving another 9 feet. Clear all 10 crates of the ball bearing. Hence the box count= 16

Step 3-Moving the remaining 15 feet and reach 3 barrels along the far side wall and remove 2 of them. Hence the box count= 18

Step 4-Turn around and come straight back.

Hence the total no of box removed= total box count= 18
