Question

A person makes a loud sound and hears the echo of this sound 1.2s later .calculate how far the person is from the object causing the echo assume that the speed of sound is 330m/s calculate the distane

Answer 1

198m

Step-by-step explanation:

Distance = speed x time

. d = 330m/s x 1.2s = 396m

This is the distance travelled by the sound from the person to the object and then back to the person. To get the distance from the person to the object, we would have to divide by 2.

. distance = 396 / 2 = 198m
