Algebra.Com's Answer #117224 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! K takes less time than M to travel a distance of 30 miles. K travels 1/3 mile per hour faster than M. If x is K's rate of speed in miles per hour then find K's time for the distance in terms of x \n" ); document.write( ". \n" ); document.write( "Let x = K's rate of speed \n" ); document.write( ". \n" ); document.write( "This problem you must apply the \"distance formula\": \n" ); document.write( "d = rt \n" ); document.write( "where \n" ); document.write( "d is distance \n" ); document.write( "r is rate or speed \n" ); document.write( "t is time \n" ); document.write( ". \n" ); document.write( "For, k to travel 30 miles: \n" ); document.write( "Solving the formula for t: \n" ); document.write( "d = rt \n" ); document.write( "t = d/r \n" ); document.write( ". \n" ); document.write( "K's time: \n" ); document.write( "t = 30/x hours (I believe this is what the problem is asking for) \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( " |
