Question Stacy is painting her bedroom. She is able to paint 34 of the bedroom in 3 hours. At this rate, how long will it take her to paint the entire room?(1 point)

Question

A. 6 hours
B. 9/4 hours
C. 4 hours
D. 12 hours

Answer 1

To find the answer, divide the total time it takes to paint the entire room by the amount of the room that can be painted in one hour.

Let x be the number of hours it will take Stacy to paint the entire room.
Then, the amount of the room that can be painted in one hour is 1/x, and the amount of the room that can be painted in 3 hours is 34/3.

So, 1/x = 34/3
To find x, cross multiply:
3 * 1 = 34 * x
3 = 34x
x = 3/34

Therefore, it will take Stacy 3/34 of an hour to paint the entire room, which is equal to 9/4 hours.
The answer is B. 9/4 hours.
