Please help with the following scenario and also assist with questions:

Rapid Transit System employs drivers for its bus routes. The drivers are paid for a 40-hour work week. From Monday through Friday, the drivers work split shifts, and they are compensated for two 30-minute breaks during their shifts. Because of the nature of their work, drivers who take their lunch break at Point A are required to travel to Point B to start the second part of their work shift. Drivers are only compensated for 30 minutes of travel time, regardless of whether or not additional time is needed to reach Point B. The suburban route drivers are upset because the suburban route average travel time is 40 minutes during rush hour. This means that drivers for the suburban routes average 50 minutes per week of uncompensated travel time.
