Lizzy: Carson is a night security guard. He's supposed to patrol the outside of a warehouse that's 600 feet long and 400 feet wide. If Carson is supposed to circle the warehouse 10 times, but gets tired and skips 2 times, how far does he walk in one night?.
Me: Hmmm, let me think. I think this is the detailed solution:
First find the total distance Carson walks along the warehouse's long sides: 600 feet / side * 2 sides = 1200 feet. Then find the total distance Carson walks along the warehouse's short sides: 400 feet / side * 2 sides = 800 feet. Add those two amounts to find the total distance walk in one circle: 1200 feet + 800 feet = 2000 feet. Then find the number of circles Carson actually walks: 10 circles - 2 circles = 8 circles. Then multiply the distance of one circle by the number of circles Carson makes: 2000 feet / circle * 8 circles = 16000 feet. Final answer: 16000.
