How much time for 1 carpenter to frame the house? Analyze according to rate as jobs per hour.
14 carpenters, 40 hours.
1 carpenter, 40*14 hours.
Those are for "ONE JOB".
rate for 1 carpenter is jobs per hour.
Now, you have 34 carpenters working together to do this job. The rate of this group of carpenters is jobs per hour.
