🔍 Key Concepts

• Fathom-to-feet conversion (1 fathom = 6 feet) • What a fathometer actually displays (depth of water, not height of tide) • Rounding depth values when converting from feet to fathoms

💭 Think About

• Imagine you already know the depth in feet at 1750 from a tide or depth problem. How would you change that number into fathoms for the fathometer setting? • If you divide feet by 6 to get fathoms, where would that put your result roughly among the answer choices (e.g., close to 10, close to 15, or much larger)? • Which options can you eliminate as clearly too shallow or too deep for a typical mid‑tide type situation once converted from feet?

✅ Before You Answer

• Confirm you’re thinking in feet to fathoms, not meters to fathoms. • Make sure you use 1 fathom = 6 feet before comparing to the answer choices. • Check whether any answer is unrealistic given a likely harbor or coastal depth at that time in the tide cycle.
