document.write( "t varies INVERSELY as v \r\n" );
document.write( "That is:  t = k/v\r\n" );
document.write( "Given: \r\n" );
document.write( "t = 4 h when v = 45mph\r\n" );
document.write( "   4 h= k/45mph,  \r\n" );
document.write( "find v when t = 5 h \r\n" );
document.write( "      t = k/v  0r v = k/t \r\n" );
document.write( "                  v =  = 36mph\r\n" );
