At an airport, the security screening process include the following operations:

Activity 1, verifying ID and boarding pass, takes 36 seconds per passenger.

Activity 2, searching the passenger for metal objects using a metal detector, takes 35 seconds per passenger.

Activity 3, running the carry-on luggage through an X-ray machine, takes 35 seconds per passenger.

Each activity is performed by a different inspector. All of them must be performed for each passenger. Assume that ID verification must be completed first. Then, an inspector can search the passenger for metal objects while the luggage goes through the X-ray machine (which is watched by a different inspector).

If passengers arrive at the screening process every 55 seconds, what is the utilization (in percentage) of the operator in charge of Activity 2?

Note:

1. Round your final answer to 2 decimal place.
2. Provide your answer as a percentage but do not include the % symbol. For example, if the utilization is 50.123%, enter 50.12.
