For 20 stars. karen started painting the walls at 9: 25 am, and she said that she would finish the job at 2: 35 pm. her mother said that three fourths of that time was enough to paint the walls. however, when karen finished the job, they noticed that it actually took her 2/3 of an hour longer than the time predicted by the mother. how much longer did karen predict it would take then the time it actually took her to complete the job (what part of an hour)?

she said that she would finish the job at = 2:35 pm
