Answer: 445.5 minutes

Step-by-step explanation:

Hi, to answer this we have to apply a proportion:

Proportion: square feet / time (minutes)

Tim installs 50 square feet of his floor in 45 minutes: 50/45

For 495 square feet: 495/x

Where x is the time it takes Tim to install 495 square feet of his floor.

50ft/45min = 495ft/x min

Solving for x

x = 495 / (50/45)

x= 445.5 minutes

Answer:

9 hrs and 10 mins

Step-by-step explanation:

We can convert this into a proportion. 50/45 = x/495. Cross-multiply to get 45x = 50*495. Divide both sides by 45 to get x = 50*11 = 550 minutes or 9 hrs and 10 mins
