Danube Delta Tourists and Boats: A Tricky Math Problem!

Hey guys! Let's dive into this interesting mathematical problem about tourists visiting the beautiful Danube Delta. This problem involves a bit of logical thinking and some basic algebra to figure out the number of tourists and boats. So, buckle up, and let’s get started!

Understanding the Problem

Okay, so the problem states that a group of tourists wants to explore the Danube Delta. The challenge arises when they try to figure out how to transport everyone using boats. Here’s the breakdown:

  • Scenario 1: If they put 4 tourists in each boat, 4 tourists are left behind on the shore.
  • Scenario 2: If they put 5 tourists in each boat, 2 boats remain empty.

The question we need to answer is: How many tourists are there in total, and how many boats are available?

To solve this, we need to use a bit of algebra. Let’s break down the problem into equations.

Setting up the Equations

Let’s use some variables to represent the unknowns:

  • Let T be the total number of tourists.
  • Let B be the total number of boats.

Now, let’s translate the given information into mathematical equations.

Equation 1: Scenario 1

In the first scenario, when 4 tourists are in each boat, 4 tourists remain on the shore. This means that the number of tourists can be represented as:

T = 4 * (number of boats used) + 4

The “number of boats used” in this case is the total number of boats, B. So, the equation becomes:

T = 4B + 4

Equation 2: Scenario 2

In the second scenario, when 5 tourists are in each boat, 2 boats remain empty. This means that only B - 2 boats are used. So, the number of tourists can also be represented as:

T = 5 * (number of boats used)

Substituting the “number of boats used” with B - 2, the equation becomes:

T = 5(B - 2)

Solving the System of Equations

Now we have a system of two equations:

  1. T = 4B + 4
  2. T = 5(B - 2)

To solve this system, we can use the substitution or equalization method. Let’s use the equalization method since both equations are equal to T.

Step 1: Equalize the Equations

Since both equations equal T, we can set them equal to each other:

4B + 4 = 5(B - 2)

Step 2: Solve for B

Now, let’s solve for B:

4B + 4 = 5B - 10

Subtract 4B from both sides:

4 = B - 10

Add 10 to both sides:

B = 14

So, there are 14 boats in total.

Step 3: Solve for T

Now that we have the number of boats, we can substitute B into either equation to find the number of tourists. Let’s use the first equation:

T = 4B + 4

Substitute B = 14:

T = 4 * 14 + 4

T = 56 + 4

T = 60

So, there are 60 tourists in total.

The Solution

Therefore, there are 60 tourists and 14 boats.

Verification

Let's quickly verify if our solution is correct by plugging the values back into the original scenarios:

  • Scenario 1: If 4 tourists are in each boat, then 60 tourists would need 60 / 4 = 15 boats. Since there are only 14 boats, 4 tourists are left behind (60 = 4 * 14 + 4). This checks out!
  • Scenario 2: If 5 tourists are in each boat, then 60 tourists would need 60 / 5 = 12 boats. Since there are 14 boats, 2 boats remain empty (14 - 12 = 2). This also checks out!

Why This Problem is Interesting

This problem is a classic example of how mathematical thinking can be applied to real-life situations. It involves translating word problems into algebraic equations, which is a crucial skill in problem-solving. Plus, it’s a fun way to engage with numbers and logic!
