One man-hour is equivalent to one person working at a normal pace for how many minutes?

One man-hour is defined as the amount of work done by one person in one hour. Since one hour is equivalent to 60 minutes, it follows that one man-hour is also equivalent to one person working for 60 minutes at a normal pace. This definition is widely used in work-scheduling, project management, and labor calculations, making it a fundamental concept in understanding work hours and productivity metrics. Thus, the correct answer reflects this standard measurement of time related to work.
