Question

A sound wave traveling at 343 m/s is emitted by the foghorn of a tugboat. An echo is heard 2.60 s later. How far away is the reflecting object?

Answer 1

Hope it helps......thanks

Answer 2

$s = d \div t \\ d = s \times t \\ s = 343 \\ t = 2.60 \\ so \\ d = s \times t \\ d = 343 \times 2.60 \\ d = 891.8$
