Answer 1

Ответ:

341*2*0,5=341 метр. Все просто и успехов в науках.

Answer 2

Calculating the Distance of the Person from the Rock

To calculate the distance of the person from the rock, we can use the formula:

Distance = Speed × Time

Given: - Speed of sound in air = 341 m/s - Time for the echo to return = 2 seconds

Using the given values, we can calculate the distance.

Calculation

Distance = Speed × Time Distance = 341 m/s × 2 s Distance = 682 meters

So, the person was standing approximately 682 meters away from the rock when they heard their echo.

This calculation is based on the speed of sound in air and the time it took for the echo to return
