Question

Tyler is making a wooden post that is 3.5 ft in length. He places marks 1 1/3 in apart from the post. After making 20 marks. Tyler says there is between 15 in. And 16 in. Of post that has not been marked.

Answer 1

Yes, Tyler is right.

Explanation:

Given that:

Length of wooden post = 3.5 feets

Position of tick mark = 1 1/3 inch apart

3.5 feets to inches

3.5 * 12 = 42 inches

Tick mark placed at 1 1/3 inch apart :

Number of tick parks made = 20

Total inches marked = (1 1/3 * 20) = (4/3 * 20) = 26.667 inches marked

Inches leg unmarked : 42 - 26.667 = 15.333333 inches

Hence, Tyler is correct.
