The echo caused by a rifle shot was heard by the hunter in 5s. At what distance is the obstacle? if the temperature is 0 degrees Celsius

Data of the problem: t (time of movement of the sound wave before the obstacle and after reflection from it) = 5 s.

Reference values: V (speed of sound in air at 0 ºС) = 331 m / s.

The distance between the hunter and the obstacle is determined by the formula: S = V * t / 2.

Let’s make a calculation: S = 331 * 5/2 = 827.5 m.

Answer: The obstacle is located at a distance of 827.5 m from the hunter.
