Tier 4 — Challenge 001 — The Echo Ridge Problem

You stand between two cliffs: Cliff A and Cliff B. 
You clap your hands and hear **two echoes**:

• The first echo arrives after **2.4 seconds** 
• The second echo arrives after **3.8 seconds**

Assume:
• Speed of sound ≈ **340 m/s** 
• You are standing **somewhere between the two cliffs**, not centred

Question: 
How far are you from each cliff?

Explain your reasoning clearly.
