You could paint 8 roses in seconds, just need some time for the paint to dry afterwards.
Caroline can paint half the fence in 3 hours and Lily can paint half the fence in 2 hours, so it will take a total of 5 hours for them to paint the fence while working together.
It would take them 4 hours to paint the house together.
Mrs Kelley wants to paint her classroom. If Mrs. Kelley works alone, it will take her 2 hours to paint her room. If Mrs. McCartney painted the room alone, it would take her 4 hours to paint the room. If Mrs. Kelley can convince McCartney to help her, how long will it take them to paint the room together (in hours and minutes)?
Assuming all work at the same speed, all the time, 8 people will paint twice as fast; thus, you can divide the total time in 2.
5400/115 = just under 47 hours, assuming you don't need any sleep!
8 hours...think of it as a ratio: 5/10=4/?
if sally can paint a house in 4 hours and john can paint the same house in 6 hours, how long will it take for them to paint the house together?
Multiply 3 and 5 to get a Least Common Multiple. 15. So you find how many rooms can Alvin paint in 15 hours (5 rooms). Same with Bernie (3 rooms). That means they can paint 8 rooms in 15 hours. Since you want to find "how long it would take," you flip the rate over. In 15 hours they can paint 8 rooms. Reduce if you want, 15/8= 1.875 hour to paint one room.
The way you calculate this (assuming that both work at constant speed) is:* Calculate what part of the house each person can paint in an hour. * Add both fractions together, to calculate what part of the house you can paint together. * Take the reciprocal of this last result, to calculate the number of hours.
