Answer 1

v = 344.1 m / s

d = 1720.5 m

Step-by-step explanation:

For this problem we must calculate the speed of sound in air at 22ºC

v = 331 RA (1+ T / 273)

we calculate

v = 331 RA (1 + 22/273)

v = 344.1 m / s

the speed of the wave is constant,

v = d / t

d = v t

we calculate

d = 344.1 5

d = 1720.5 m
