    2/3 of an hour = 40 minutes

    3/4 of 40 = 30 minutes

    40 - 30 = 10

    So, it took Bethany 10 more minutes to complete her science homework than her math homework.

    10 more minutes

    This is because 2/3 of an hour is 40 minutes and 3/4 of 40 is 30. 40-30=10. Therefore it took Bethany 10 more minutes to do her science homework than it did her math.
