Martha can paint a room in 2 hours. jamie can paint the same room in 6 hours. how long, to the nearest tenth of an hour, will it take them to paint the room together

1.5 hours

Step-by-step explanation:

we know that

1) Martha can paint a room in 2 hours

so

Martha can paint the 100% of the room in 2 hours

Find out what percentage of the room she can paint in an hour

using proportion

2) Jamie can paint a room in 6 hours

so

Jaimie can paint the 100% of the room in 6 hours

Find out what percentage of the room she can paint in an hour

using proportion

3) In one hour Martha and Jamie can paint

so

using proportion

Find out how long will it take them to paint the 100% room together

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
