50 inches

The length of the track that Marc builds can be represented by the formula 4x, where x is the number of 4-inch pieces he uses. The length of the track that Aki builds can be represented by the formula 10x, where x is the number of 10-inch pieces he uses.
The lengths of the tracks will be the same when 4x = 10x. Solving this equation, we find:
4x = 10x
6x = 0
x = 0
Therefore, the tracks will be the same length when they have both built 0 pieces. The length of their tracks will be 0 inches, so the answer is 0 inches.
