MathPup Railway - Feet

MathPup's railway has track missing on one of its bridges. Determine the correct size of track needed to fill in the spaces and drop it in so MathPup can get safely across.

Click on the piece of track at the bottom of the screen to increase its size to the needed length. Once you have the correct size needed, click the DROP IT button to drop it in place on the track (below the flashing red arrow). Click the RESET button to reset the track piece.
