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.
45 days
Assuming all of the 4 people worked at the same pace originally, it would take two people 6 days.
about how many years would it take for $1000 to become $2000 with an interest rate of 7.2
5000 ÷ 2000 = 2.5 hours
It would take 9 men 42 days.
It would take them 4 hours to paint the house together.
2000 miles
At the same rate of painting, it would take 4 hours.
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)?
Divide 2000 miles by 25 mph to get the answer. It would take 80 hours to go 2000 miles at 25 mph.
Technically, if you wouldn't to do it right then it would take about 1 hour. That is just a close estimate.
One year and then they would start at the begining again.
4-6 hours if you used a primer.
I would say when it's been dry for an hour or so.
it takes 2000 years
