If these birds travel on an average speed of 350 km/ day, find out in how many days each of the species will take to complete the round trip.

To provide a comprehensive solution, let's first break down the problem.

1. Break Down the Problem

1. We need to find out the total distance of the round trip for each bird species.
2. We then need to calculate how many days it will take for each species to complete the round trip given the average speed of 350 km per day.

2. Relevant Concepts

• The formula to calculate travel time is: $\text{Time} = \frac{\text{Distance}}{\text{Speed}}$

3. Analysis and Detail

1. Determine the total distance for the round trip for each species (this information is missing in your question, so I will denote the total distance as $D$).
2. Calculate the travel time using the formula: $\text{Days} = \frac{D}{350}$ Here, $D$ will vary depending on each bird species.

4. Verify and Summarize

To summarize, the time required for each species to complete the round trip can be represented as: $\text{Days} = \frac{D_{species}}{350}$ Where $D_{species}$ is the total distance for the round trip of each bird species.

Final Answer

Each bird species will take $\frac{D_{species}}{350}$ days to complete the round trip, where $D_{species}$ is the round trip distance for that species. Please provide the exact distance for a specific calculation.
