\n" ); document.write( "Walking up a 4-mile trail, a hiker travels 1 mph slower than walking down the same trail at speed \"highlight%28x%29\"
\n" ); document.write( "Note: D = rt OR t = D/r
\n" ); document.write( "Question states*** total of 5 hours is spent walking up and down the trail
\n" ); document.write( " \"+4%2F%28x-1%29+%2B+4%2Fx+=+5hr\" |Multiplying thru by x(x-1) so as all denominators = 1
\n" ); document.write( " 4x + 4(x-1) = 5x(x-1)
\n" ); document.write( " 4x + 4x - 4 = 5x^2 - 5x
\n" ); document.write( " 5x^2 - 13x + 4 = 0
\n" ); document.write( "\"x+=+%2813+%2B-+sqrt%2889+%29%29%2F%2810%29+\"
