2)12:12=1(км/ч)
Ответ: ворона будет лететь со скоростью 1 км/ч

Answer 2

Problem Analysis

We are given that a sparrow flew a distance of 12 km in 4 hours, while a magpie took 8 hours longer to cover the same distance. We need to determine the speed at which the magpie is flying.

Solution

To find the speed at which the magpie is flying, we can use the formula:

Speed = Distance / Time

Let's calculate the speed of the sparrow first. The sparrow flew a distance of 12 km in 4 hours, so its speed is:

Sparrow's Speed = 12 km / 4 hours = 3 km/h.

Now, let's calculate the time it took for the magpie to cover the same distance. The magpie took 8 hours longer than the sparrow, so its time is:

Magpie's Time = Sparrow's Time + 8 hours = 4 hours + 8 hours = 12 hours.

Finally, we can calculate the speed of the magpie using the formula:

Magpie's Speed = Distance / Time = 12 km / 12 hours = 1 km/h.

Therefore, the magpie is flying at a speed of 1 km/h.

Answer

The magpie is flying at a speed of 1 km/h.
