Algebra.Com's Answer #732806 by greenestamps(13203)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "The responses from the other tutors show a perfectly good algebraic solution to your problem. \n" ); document.write( "Here is another solution method that I like to use for this kind of problem. \n" ); document.write( "The hour hand makes 1 revolution every 12 hours; the minute hand makes 12 revolutions every 12 hours. \n" ); document.write( "So there are 11 times in every 12-hour period when the hour and minute hands are pointing in the same direction. \n" ); document.write( "Since both hands move at constant rates, the times when the hands are pointing in the same direction will be separated by 12/11 hours. \n" ); document.write( "The two hands are pointing in the same direction at 12 o'clock. \n" ); document.write( "The time between 8 and 9 o'clock when the hands are pointing in the same direction is 8*(12/11) hours after 12 o'clock. \n" ); document.write( "8*(12/11) hours = 8 and 8/11 hours \n" ); document.write( "8/11 hours = 480/11 minutes = 43 7/11 minutes \n" ); document.write( "7/11 minutes = 420/11 seconds = 38 2/11 seconds \n" ); document.write( "The two hands are pointing in the same direction at 8:43:38 2/11 \n" ); document.write( " |
