Algebra.Com's Answer #814338 by robertb(5830)![]() ![]() You can put this solution on YOUR website! In fact, contrary to what one of the tutors mentioned below, \n" ); document.write( "if the student finished 1/3 (one-third) of the assignment BETWEEN 6 pm and 7:30 pm (assuming same day), \n" ); document.write( "then it will still be possible for him to turn the assignment in on time, working at the same rate as in the first third. \n" ); document.write( "(Which basically says he worked at a constant rate through out.). \n" ); document.write( "E.g., if 1/3 of the assignment was finished at 6:20 pm, then he would need just another 40 minutes to finish the job! \n" ); document.write( "The issue arises is if he finished 1/3 of the assignment before but close to 7:30 pm. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "That said, the FLAW of the problem is in the CHOICES. \n" ); document.write( "If x = # hours from 6 pm 1/3 of the assignment was done, then \r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the LATEST time in which the assignment could be turned in being 10:30 pm.\r \n" ); document.write( "\n" ); document.write( "---------------------------------------------------------------------\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "If the starting time was AFTER BUT CLOSE TO 6 pm, then that doesn't exclude the possibility of submitting on time, at all. \n" ); document.write( "But as ikleyn pointed out, even if you don't know the starting time, if it was BEFORE BUT CLOSE to 6pm \n" ); document.write( "then that still does NOT preclude submitting on time! \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "But I do agree that the problem is FLAWED. \n" ); document.write( " |
