Question 2.

Tom and Lionel climb a tree. They have to climb a ladder first, then up to the branches. The ladder is 6 feet long. Tom climbs 4- feet from the ladder to a branch. Lionel climbs 2 feet from the ladder to another branch. What is the total distance that Tom and Lionel have climbed?

Answer:

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.

Tom climbs 4- feet from the ladder to a branch.

Lionel climbs 2 feet from the ladder to another branch.

Distance climbed by Tom = 6 + 4 = 10 feet

Distance climbed by Lionel = 6 + 2 = 8 feet

Total distance = 10 + 8 = 18 feet

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.
