    Answer:Bethany started het homework at 3.05 PM approx 3 PM.

    Step-by-step explanation:

    The number of problems completed by Bethany = 25

    The time taken to complete 1 problem = 3 minutes

    The time taken to complete 25 problems = 25 * 3 = 75 minutes

    Bethany finished her math homework at 4:20 p. M.

    So she started 75 minutes 4.20 PM, (i. e) 3.05 PM or

    approx around 3 PM.
