A section of a boardwalk is made using 15 boards. Each board is 914 inches wide. The total width of the section is 144 inches. The spacing between each board is equal. What is the width of the spacing between each board? Write your answer in simplest form.

Answer 1

Assume you mean 9.14 in wide

there is one less space than board

15 boards
14 spaces

so

15 * 9.14 + 14 * x = 144

137 + 4 x = 144

4 x = 7

x = 7/4 = 1.75 in
