It takes 60 seconds to walk up a broken escalator and 40 seconds to ride up the same escalator when it is moving.
\n" ); document.write( " How long will it take to walk up the same escalator when it is moving?
\n" ); document.write( ":
\n" ); document.write( "Assume the length of the escalator is 60 ft
\n" ); document.write( "then
\n" ); document.write( "Walking: 1 ft/sec
\n" ); document.write( "moving: 60/40 = 1.5 ft/sec
\n" ); document.write( "walking & moving 2.5 ft/sec
\n" ); document.write( ":
\n" ); document.write( "Find the time at 2.5 ft/sec
\n" ); document.write( "t = 60/2.5 = 24 seconds walking & moving \n" ); document.write( "
\n" );
