How long will it take a howler monkey call to get to another howler monkey if they were 2 km apart

To solve the question we proceed as follows;

time=distance/speed

distance between the monkeys is 2km=2000m

But the speed of sound = 330 m/s

Therefore the time taken for a howler monkey to get to the other will be:

time=2000/330

=6.1 seconds

The answer is 6.1 seconds
