Answer:
72 inches
Step-by-step explanation:
Due to the programming error, the robot first moves to the right and then to the left. The second time it moves to the right, it increases its distance by 1 foot to the right and then turns back and moves to the left, reaching the starting position again.
The patterns is as follows:
move 1: moves to the right by 1 foot.
moves 2: moves to the left.
moves 3: moves to the right by 2 feet.
moves 4: moves to the left
moves 5: moves to the right by 3 feet.d
moves 6: moves to the left
moves 7: moves to the right by 4 feet.
moves 8: moves to the left
moves 9: moves to the right by 5 feet.
moves 10: moves to the left
moves 11: moves to the right by 6 feet.
We see that in the end, the robot has managed to only move 6 ft. Since 1 ft = 12 inches, 6 ft = 6* 12 = 72 ft.
So, the robot has painted 72 inches of the fence before Kiteretsuki returns.
