## 📊 Given Data:

We are given two tables:

Table 1: Distance from Cape May (miles) → Ocean Depth (fathoms)


| Distance from Cape May (miles) | Ocean Depth (fathoms) |
|-------------------------------|------------------------|
| 0 | 100 |
| 125 | 1,000 |
| 325 | 2,000 |
| 475 | 2,500 |
| 650 | 2,000 |
| 1,125 | 2,800 |
| 1,300 | 3,125 |
| 1,425 | 2,900 |
| 1,675 | 2,000 |
| 1,800 | 1,500 |
| 1,900 | 1,200 |
| 2,000 | 1,100 |
| 2,150 | 1,100 |

Table 2: Distance from Cape May (miles) → Distance from Cape Town (miles) → Ocean Depth (fathoms)


| Distance from Cape May (miles) | Distance from Cape Town (miles) | Ocean Depth (fathoms) |
|-------------------------------|----------------------------------|------------------------|
| 2,200 | 3,500 | 750 |
| 2,325 | 3,325 | 700 |
| 2,450 | 3,200 | 550 |
| 2,475 | 3,175 | 0 |
| 2,525 | 3,125 | 0 |
| 2,700 | 2,950 | 2,000 |
| 2,725 | 2,925 | 2,000 |
| 2,800 | 2,850 | 2,000 |
| 3,150 | 2,500 | 2,700 |
| 3,300 | 2,350 | 2,300 |
| 3,400 | 2,250 | 1,500 |
| 3,425 | 2,225 | 100 |
| 3,475 | 2,175 | 0 |
| 3,500 (Portugal) | 2,150 (Cape Town) | 0 |

## Question 1:
> Find the minimum and maximum depths in fathoms, where 1 fathom equals 6 feet. Convert these measurements to feet. What was the maximum depth measured?

Step 1: Scan all ocean depth values in both tables.



From Table 1:
- Depths: 100, 1000, 2000, 2500, 2000, 2800, 3125, 2900, 2000, 1500, 1200, 1100, 1100

From Table 2:
- Depths: 750, 700, 550, 0, 0, 2000, 2000, 2000, 2700, 2300, 1500, 100, 0, 0

So, minimum depth = 0 fathoms
Maximum depth = 3,125 fathoms (from Table 1 at 1,300 miles from Cape May)

Step 2: Convert to feet (since 1 fathom = 6 feet)



- Minimum depth in feet = 0 × 6 = 0 feet
- Maximum depth in feet = 3,125 × 6 = 18,750 feet

Final Answer for Question 1:


> Minimum depth: 0 fathoms (0 feet)
> Maximum depth: 3,125 fathoms (18,750 feet)
> The maximum depth measured was 18,750 feet.

## Question 2:
> What is the maximum ocean depth between New Jersey and Portugal? In miles?

This question is a bit tricky — it asks for the maximum ocean depth (which we already found: 3,125 fathoms), but then adds “in miles?” — which doesn’t make sense because depth is not measured in miles; it’s measured in feet or fathoms.

However, looking at context, it’s likely asking:
> At what distance (in miles from Cape May) was the maximum depth measured?

Because the table gives distances from Cape May, and we’re mapping the ocean floor along that route.

From Table 1, the maximum depth of 3,125 fathoms occurs at 1,300 miles from Cape May.

So, while the depth itself isn’t “in miles,” the location of the maximum depth is 1,300 miles from Cape May (New Jersey).

> (Note: Cape May is in New Jersey, and Portugal is the endpoint — so this is along the Atlantic crossing.)

Final Answer for Question 2:


> The maximum ocean depth (3,125 fathoms) was measured at 1,300 miles from Cape May (New Jersey).

## 🧭 Bonus: Understanding the Map

You’re essentially plotting a cross-section of the Atlantic Ocean floor from Cape May (USA) to Portugal (Europe), passing near Cape Town (South Africa) — but note: the second table seems to be continuing the transect past the Mid-Atlantic Ridge toward Africa/Europe.

The data shows:
- Shallow near the coast (0–100 fathoms)
- Deepens rapidly to ~3,125 fathoms (the deepest point)
- Then shallows again toward the European/African continental shelf (0 fathoms near Portugal/Cape Town)

This reflects the shape of the Mid-Atlantic Ridge — a mountain range under the ocean — with deep trenches on either side.

## ✍️ Summary of Answers:

1. Minimum and Maximum Depths:


- Min: 0 fathoms → 0 feet
- Max: 3,125 fathoms → 18,750 feet
- Maximum depth measured: 18,750 feet

2. Location of Maximum Depth:


- 1,300 miles from Cape May (New Jersey)
