Lizzy: Jack needs to mop the bathroom and the kitchen. If the bathroom floor is 24 square feet and the kitchen floor is 80 square feet, and Jack can mop 8 square feet per minute, how many minutes does he spend mopping?.
Me: Hmmm, let me think. I think this is the detailed solution:
First find the total floor area Jack needs to mop: 24 sq ft + 80 sq ft = 104 sq ft. Then divide the total area that needs to be mopped by Jack's mopping rate: 104 sq ft / 8 sq ft / minute = 13 minutes. Final answer: 13.
