Question 890345: If it takes a girl 12 hr to do a job, what is her rate?
Answer by Theo(13342) (Show Source):
You can put this solution on YOUR website! her rate would be 1/12 of the job per hour.
rate * time = quantity of work.
quantity of work, in this case, is 1 job.
time is 12 hours.
rate * time = quantity of work becomes:
rate * 12 hours = 1 job
divide both sides of this equation by 12 to get:
rate = 1/12 of the job per hour.
at the rate of 1/12 of the job per hour, she will take 12 hours to complete tghe job.
