Let the distance from the base to the mountain top = x
\n" ); document.write( "Going up speed was 2 miles per hour
\n" ); document.write( "Time taken = x/2
\n" ); document.write( "Going down speed was 3 miles per hour.
\n" ); document.write( "Time taken = x/3
\n" ); document.write( "Total time taken is x/2+x/3 = 10
\n" ); document.write( " (3x+2x)/6 = 10
\n" ); document.write( " 5x = 60
\n" ); document.write( " x = 60/5
\n" ); document.write( " x = 12 miles\r
\n" ); document.write( "\n" ); document.write( "
