Question

(1) Sam went to the hardware store and bought two

identical wooden planks. When Sam placed the
planks end to end, the total length was .78 meters
long. How long was each plank?

Answer 1

0.39 meters

Explanation:

If the two planks were identical, that means the total length divided by two would equal the length of one plank.

0.78 / 2 = 0.39
