If 4 technicians handle 28 outages in 7 hours, what is the average outages per hour per technician?

• A. 0.5
• B. 1
• C. 1.5
• D. 2

Answer: (B)

Think of it as total outages spread evenly over all technician-hours. There are 4 technicians working 7 hours each, giving 4 × 7 = 28 technician-hours. With 28 outages in that period, the rate is 28 outages / 28 technician-hours = 1 outage per technician per hour. So the correct average is 1 outage per hour per technician.
