Final answer:
Brenda's daily commute is not compensable under the Portal-to-Portal Act, which her boss could cite concerning her inquiry about compensation for travel time.
Step-by-step explanation:
Brenda's boss would most likely cite the Portal-to-Portal Act, an amendment to the Fair Labor Standards Act, which addresses work-related travel time. According to this Act, typical home-to-work and work-to-home commute time is not considered compensable working time. Therefore, her hour-and-a-half daily commute would generally not be covered by the employer.
