Question

Tim installs 45 square feet of his floor in 50 minutes. At this rate, how long does it take him to install 495 square feet?

Answer 1

Answer:

550 minutes

Explanation:

45/5=9 and 50/5=10

9 square feet per 10 minutes

495/9=55

^total square feet divided by square feet per 10 minutes. Quotient shows the amount of times the 9 square feet per 10 minutes cycle is repeated meaning we multiple 55 by 10.

55*10=550 minutes
