Question

Charla wants to cover a rectangular area of her driveway with a picture using chalk. If she completes 23 of the area in 12 hour, how long will it take her to complete the entire picture?(1 point) Responses 13 of an hour 1 third of an hour 12 of an hour 1 half of an hour 34 of an hour 3 fourths of an hour 1 hour

Answer 1

To find out how long it will take Charla to complete the entire picture, you can set up a proportion:

Complete area / Time taken to complete = Partial area / Time taken to complete 23

Let x be the time taken to complete the entire picture. The proportion can be written as:

1 / x = 23 / 12

To solve for x, cross-multiply:

12 = 23x

Divide both sides by 23:

x = 12 / 23

So, it will take Charla approximately 12/23 of an hour to complete the entire picture.
