Question

a sound wave traveling at 343 m/s is emitted by the foghorn of a tugboat. an echo is heard 1.60 s later. how far away is the reflecting object

Answer 1

274.4 meters

Step-by-step explanation:

As speed = distance/time, we can customize this formula to speed = distance*2/time, as its and echo it travels to the object and comes back to the place where the sound came from travelling that distance twice.

So, speed = distance*2/time

343 = 2x/1.6

343*1.6= 2x

548.8= 2x

x = 274.4 meters
