  2. Explanation

    Step1: Calculate total pre-break work time

    $7:00\ \text{am} - 5:00\ \text{am} = 2\ \text{hours}$

    Step2: Calculate total post-break work time

    $7:00\ \text{pm} - 12:30\ \text{pm} = 6.5\ \text{hours}$

    Step3: Sum work segments minus breaks

    $2 + 6.5 + (12:00\ \text{pm} - 7:30\ \text{am}) = 2 + 6.5 + 4.5 = 13\ \text{hours}$
