A hiker shouts when he is at the top of a mountain. He hears an echo 2.4 seconds later from the sounds reflection off a nearby mountain. Calculate how far he is from the nearby mountain. (Assume speed of sound in air is 340 m/s)

To calculate the distance between the hiker and the nearby mountain, we can use the formula: distance = (speed of sound) * (time taken for echo to return) / 2.

Given that the speed of sound in air is 340 m/s and the time for the echo to return is 2.4 seconds, we can substitute these values into the formula.

distance = (340 m/s) * (2.4 s) / 2
distance = 408 m

Therefore, the hiker is approximately 408 meters away from the nearby mountain.
