Question 890345: If it takes a girl 12 hr to do a job, what is her rate?

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.
