Answer:
Step-by-step explanation:
If the howler monkeys were 2 km apart (2,000 meters), we can calculate the time it would take for the sound to travel from the calling monkey to the other monkey:
Distance between the monkeys = 2,000 meters
Speed of sound in air = 343 meters per second
Time = Distance / Speed
Time = 2,000 meters / 343 meters per second
Time ≈ 5.83 seconds
So, it would take approximately 5.83 seconds for the sound of the howling monkey to travel from one monkey to another if they were 2 km apart.
