Answer
Marlya's distance from the shore is \( y = 2x \). Olga's distance from the shore is \( y = 1.5x + 10 \).
Solution
To determine the correct equations for Marlya's and Olga's distances from the shore, let's analyze the given information and the provided options.
### Given:
- **Variables:**
- \( x \): Number of seconds
- \( y \): Number of meters
### 1. **Marlya's Distance from the Shore**
The equation provided for Marlya is:
\[
y = 2x
\]
**Interpretation:** This means that Marlya moves away from the shore at a constant speed of 2 meters per second.
### 2. **Olga's Distance from the Shore**
We need to choose the correct equation that represents Olga's distance from the shore. The options provided are:
1. \[
x = 1.5y + 10
\]
2. \[
y = 1.5x
\]
3. \[
x = 1.5y
\]
4. \[
y = 1.5x + 10
\]
**Analysis of Options:**
- **Option 1 (\(x = 1.5y + 10\)) and Option 3 (\(x = 1.5y\))**:
- These equations express \(x\) in terms of \(y\), which is less conventional for representing distance over time. Typically, distance (\(y\)) is expressed as a function of time (\(x\)).
- **Option 2 (\(y = 1.5x\))**:
- This equation suggests Olga moves at 1.5 meters per second, similar to Marlya but at a slower speed. However, it doesn't account for any initial distance difference between them.
- **Option 4 (\(y = 1.5x + 10\))**:
- This equation indicates Olga moves at 1.5 meters per second **and** starts 10 meters ahead of (or behind) the shore. The "+10" represents an initial distance offset.
**Conclusion:**
**Option 4 (\(y = 1.5x + 10\))** is the most comprehensive and appropriate equation, as it accounts for both Olga's speed and an initial distance from the shore.
### **Final Equations:**
- **Marlya:** \[
y = 2x
\]
- **Olga:** \[
y = 1.5x + 10
\]
These equations accurately represent the distances of Marlya and Olga from the shore over time.

The Deep Dive
In a fun twist of numbers, Marlya's equation \(y=2x\) tells us she swims at a steady speed of 2 meters for every second she spends in the water! So if she swims for 10 seconds, she’d be a fabulous 20 meters from the shore, dancing with the waves! Now, for Olga, the equation \(y=1.5x\) highlights her smoother sailing, covering 1.5 meters every second. If she matches Marlya's pace at 10 seconds, she’ll glide in at 15 meters. Just consider these equations a splish-splashing race against the shore!
