🎅 Calculate Santa’s Delivery Time 🎁

Get Santa’s delivery schedule in order! This program calculates how long Santa will take to deliver gifts to all houses and return to his cozy starting point at [0, 0]. The sleigh travels at a fixed speed, so let’s make sure those presents arrive on time! 🎄

📜 Task Description

Santa’s sleigh travels at a fixed speed (e.g., 10 km/h).
Each house is located on a 2D grid with coordinates, and we calculate:

1. The total distance Santa covers to visit all houses.
2. The total time needed based on the sleigh's speed.

This ensures Santa’s journey is efficient and precise. 🚀

🔢 Features

• Input:
  🎯 houses: A list of coordinates representing house locations.
  🛷 speed: Sleigh speed in km/h.

• Output:
  ⏱️ Total delivery time in hours, including the return to [0, 0].

✨ Example

Input:

Houses: [[1, 2], [3, 4], [5, 6]]
Speed: 10 km/h

Output:

1.57 hours (Santa’s total delivery time)

🚀 How It Works

1. Calculate Distance:

   • Uses the classic Euclidean distance formula to measure the journey from one point to another.

2. Visit Each House:

   • Santa stops at each house in sequence, summing up the distances.

3. Return Home:

   • Adds the distance from the last house back to [0, 0].

4. Calculate Time:

   • Divides the total distance by the sleigh’s speed to get time in hours.

5. Precision:

   • Displays the time with two decimal places for accuracy.

🧪 Testing

🎯 Sample Input
Houses: [[1, 2], [3, 4], [5, 6]]
Speed: 10 km/h

✅ Expected Output
1.57 hours

📚 Key Formula

To calculate the distance between two points:
[ \text{distance} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} ]

To calculate the time:
[ \text{time} = \frac{\text{distance}}{\text{speed}} ]
