Answer 2

Calculating the Meeting Time for the Duck and the Goose

To calculate the meeting time for the duck and the goose, we can use the concept of relative speed and distance. Since the duck and the goose are flying towards each other, their relative speed will be the sum of their individual speeds. We can then use the formula:

Time = Distance / Speed

Let's calculate the meeting time step by step.

Calculating the Duck's Speed

The duck flies from the southern sea to the northern sea in 7 days. Therefore, its speed can be calculated using the formula:

Speed = Distance / Time

The distance is from the southern sea to the northern sea, and the time taken is 7 days.

Calculating the Goose's Speed

Similarly, the goose flies from the northern sea to the southern sea in 9 days. Using the same formula:

Speed = Distance / Time

The distance is from the northern sea to the southern sea, and the time taken is 9 days.

Calculating the Meeting Time

Now that we have the speeds of the duck and the goose, we can calculate the meeting time using the relative speed of the two birds.

Relative Speed = Duck's Speed + Goose's Speed

Meeting Time = Distance / Relative Speed

By plugging in the values, we can find the meeting time for the duck and the goose.

Let's calculate the meeting time for the duck and the goose.
