Six words are to be entered, one across each row of the grid.
The colors are present to create individual regions. In each region all the letters are the same. Two adjacent regions have different letters; non-adjacent regions may or may not have the same letter regardless of same or different color.
Clues for the words in the four middle rows (rows 2-5), in random order, are:
- hot dog topping
- VCR's "go back to start" button
- language of Warsaw

A man was walking through a tunnel. He is 1/4 of the way through when he hears a train approaching the tunnel from behind him.
If he turns and runs back, he will make it out of the tunnel just as the train is entering it (and will save himself by a hair). If he goes forward to the far end of the tunnel, he will also just barely make it, emerging from the tunnel just as the train is about to catch up to him.
If the man's running speed is 7 miles per hour, how fast is the train moving?
