UP Fitness will install 3 new trapezoidal gel-resistance toners, or "trappies," which are the latest exercise

gadget specifically designed to contour upper back muscles. Clients who want to use these machines arrive at the rate of 85 per hour. The coefficient of variation of the interarrival times is 3. If all three machines are busy, UP Fitness clients use other pieces of equipment, waiting for one of the "trappies" to become available. The trappy experience is intense—120 seconds of explosive exercise intensity. The standard deviation of the usage times (measured in seconds) is quite small—only 30.

On average, how many UP Fitness clients are waiting to use a trappy? (Round to 2 decimal points)
