[Question]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?
[Answer]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. The answer is 13.

[Question]A soccer ball takes twenty minutes to inflate. Alexia and Ermias are inflating balls, with Alexia inflating 20 balls and Ermias inflating 5 more balls than Alexia. Calculate the total time in minutes they took to inflate all the soccer balls.
[Answer]To inflate a soccer ball, it takes 20 minutes, and if Alexia inflated 20 soccer balls, she took 20 * 20 = 400 minutes. Ermias has 5 more soccer balls than Alexia, meaning she has a total of 20 + 5 = 25 soccer balls. If each soccer ball takes 20 minutes to inflate, Ermias took 25 * 20 = 500 minutes to inflate all the soccer balls she had. Alexia and Ermias took 400 + 500 = 900 minutes to inflate all the soccer balls. The answer is 900.
