Question

Tyler painted a wall with a length of 28 feet and a width of 12 feet in 514 hours. What is the speed, in square feet per hour, at which Tyler painted the wall?

Answer 1

Area of the wall = (28 feet) x (12 feet) = 336 square feet

Time that Tyler took = 514 hours

Speed at which Tyler tackled the tinting task =

                               (area painted) / (time taken)

                   =    (336 square feet) / (514 hours)

                   =            0.654... square foot per hour . (rounded)


And now, a Brainly Reality/Sanity Check:

-- 0.654 square foot is almost exactly the area of a standard sheet
of printer paper or notebook paper (one side of it).

-- Every time Tyler painted that much area, he took an hour to do it.

-- If he worked 24/7 without stops for sleep, food, or pits, it took him
3 weeks and 10 hours to paint the wall.

-- If he only worked Painters' Union hours ... 8 hours a day, 5 days a week ...
then the job took him 12 weeks, 45 days, and 2 hours.

-- Tyler was doing other things besides painting the wall.

Answer 2

12 feet x 28 feet = 336 square feet
336 square feet / 514 hours = 0.654 square feet per hour (to 3 sig figs)
