    2.5 hours

    Step-by-step explanation:

    1. x = hours

    (We don't know x yet, x is the answer)

    2. 60*x+125 = 70*x+100

    (60*x means Paul charge $60 per hour for x hours)

    3. Solve 70*x - 60*x = 125 - 100

    4. 10*x = 25 = > x = 25:10

    5. x = 2.5

    So Paul's money will equal George's money after 2.5 hours.
