What is the unit rate of work done by 1 man in terms of jobs per hour, if 10 men can do 1 job in 6 hours?

• A. 1/60 jobs
• B. 1/30 jobs
• C. 1/12 jobs
• D. 1/6 jobs

Answer: (B)

To determine the unit rate of work done by 1 man in terms of jobs per hour, we start with the information given: 10 men can complete 1 job in 6 hours. First, we calculate the total man-hours required to complete the job by the 10 men. If 10 men take 6 hours, the total work done in man-hours is: 10 men × 6 hours = 60 man-hours. This means that it takes 60 man-hours to complete 1 job. Now, we want to find out how much work is done by 1 man in 1 hour. Since 1 job requires 60 man-hours, it follows that 1 man would take: 60 man-hours ÷ 1 man = 60 hours to complete the job alone. Now, to find the unit rate for this 1 man in jobs per hour, we determine how much work 1 man does in 1 hour. This is calculated as follows: 1 job takes 60 hours for 1 man, which means that in 1 hour, that man would complete: 1 job ÷ 60 hours = 1/60 jobs per hour. However, since we are estimating the unit rate per

To determine the unit rate of work done by 1 man in terms of jobs per hour, we start with the information given: 10 men can complete 1 job in 6 hours.

First, we calculate the total man-hours required to complete the job by the 10 men. If 10 men take 6 hours, the total work done in man-hours is:

10 men × 6 hours = 60 man-hours.

This means that it takes 60 man-hours to complete 1 job.

Now, we want to find out how much work is done by 1 man in 1 hour. Since 1 job requires 60 man-hours, it follows that 1 man would take:

60 man-hours ÷ 1 man = 60 hours to complete the job alone.

Now, to find the unit rate for this 1 man in jobs per hour, we determine how much work 1 man does in 1 hour. This is calculated as follows:

1 job takes 60 hours for 1 man, which means that in 1 hour, that man would complete:

1 job ÷ 60 hours = 1/60 jobs per hour.
