Let us take,
\(v\) - speed of sound through seawater.
\(t\) - the time interval between transmission and reception of the ultrasound.
\(2d\) - total distance travelled by the ultrasound.
Then, by using the formula,
So,
Apply all the terms, we will get the formula to find the total distance travelled by ultrasound.
