Walk The Talk II !
I started walking on the moving walkway at a constant speed, and discovered that it took me exactly 162 seconds to go from one end to the other.
Next I started to walk against the moving walkway (the wrong way) at the same constant speed and found that it took me five times as long to go from one end to the other.
If I just walked at the same constant speed, without using the moving walkway, how many seconds would that take me to cover the same distance?
