Answer:
1715 metros
Step-by-step explanation:
Lo que debemos hacer es calcular la distancia del primer y del segundo eco.
Debemos conocer la velocidad del sonido que en términos generales es 343 m/s, por lo tanto, la distancia sería igual a:
v = d/t => d = v*t
d1 = 343*2 = 686 metros
d2 = 343*3 = 1029 metros
La separación sería la suma de ambas distancias así:
686 + 1029 = 1715
1715 metros sería la distancia de separación entre ambas montañas.
