To accommodate the largest jets, the length of an international airport runway is 1,500 m more than 50 times its width. Let w represent the width of the runway, in meters. Find an expression for the length, l, of the runway in terms of w.

Given that the length of the runway is 1,500 meters more than 50 times its width, we can express the length of the runway, \( l \), in terms of its width, \( w \).

### Step-by-step Solution:

1. **Define the variables:**
   - Let \( w \) represent the width of the runway in meters.
   - Let \( l \) represent the length of the runway in meters.

2. **Translate the given information into an equation:**
   - According to the problem, the length is 1,500 meters more than 50 times the width.

   This can be written mathematically as:
   \[
   l = 50w + 1500
   \]

### Final Expression:

The expression for the length of the runway in terms of its width \( w \) is:

\[
\boxed{l = 50w + 1500}
\]

Would you like me to explain any part of this solution further? Here are some related questions you might be interested in:

1. What would the length of the runway be if the width is 30 meters?
2. How would the expression change if the length were instead 2,000 meters more than 50 times the width?
3. If the length is 3,000 meters, what is the width of the runway?
4. How does increasing the width by 10 meters affect the length?
5. Can you create an equation involving both length and width and solve for a specific dimension?

**Tip:** Always clearly define your variables when setting up equations, as this helps in translating the word problem into mathematical expressions correctly.
