Question

find the distance between a surface and the sources of sound if speed of sound is 334m/s and echo returns from the surface in1.5sec

Answer 1

Sound goes from source reflect from surface and return back.
it covers total 2x distance
so
2x=334×1.5
x=250.5m

Answer 2

To Calculate the Distance in This Case,

We have this Formula,

2D = Vt

Or, 2D = 334m/s × 1.5s
Or, 2D = 501m
Or, D = 501m/2 = 250.5m

Therefore, the required Distance is 250.5m.
