Given,
Tom and Lionel climb a tree.
They have to climb a ladder first, then up to the branches.
The ladder is 6 feet long.

Question 1.
There are 2 boards, A and B. The total length of both boards is 28 feet. Board B is at least 5 feet longer than Board A, but the difference is not more than 12 feet. What are the possible lengths of the two boards?
Answer:
Given,
There are 2 boards, A and B.
The total length of both boards is 28 feet.
Board B is at least 5 feet longer than Board A, but the difference is not more than 12 feet.
Let Length of Board A be a
Length of Board B be b
From thee given data, these conditions can be drawn,
a + b = 28
b ≥ a + 5
b – a < 12
So, substituting a = 28 – b in b ≥ a + 5, it becomes,
Therefore,
The possible lengths of board a is 8 to 11.5 feet.
The possible lengths of board b is 16.5 to 20 feet.
