Stationary Engineer

You want to figure out how long it will take the temperature to get back to normal.

72.0 degrees - 49.3 degrees = 22.7 degrees difference
22.7 degrees / 4.5 degrees per hour = 5 hours

Once the Bazzomatic 2000 kicks in, the hospital's internal temperature will reach the normal goal temperature of 72 degrees Fahrenheit in 5 hours.

"Math is one of the more important aspects of my job," says stationary engineer Larry Berta. "While we don't have to be geniuses with numbers, it's always good to be up on these things. We have to deal with technical matters in our work, which involves numbers."
