Algebra.Com's Answer #749188 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "The solution by the other tutor shows that the statement of the problem is faulty, because the answers are not whole numbers of years. \n" ); document.write( "The other tutor correctly points out that \"two times older\" is NOT the same as \"two times as old\". Unfortunately, most people don't make a distinction between the two phrases. (I have even seen problems on practice SAT tests where the wrong interpretation of \"x times older than\" is used!) \n" ); document.write( "So the intended statement of the problem is this: \n" ); document.write( "Jamie is 5 years older than her brother. Five years ago she was 2 times AS OLD AS her brother. How old are they? \n" ); document.write( "The difference in their ages is always 5 years. So when she was twice as old as her brother, she was 10 and he was 5. Since that was 5 years ago, they are now 15 and 10. \n" ); document.write( " |
