Question

3. A stationary submarine sends a SONAR wave (speed of wave in water = 1500 m/s). A boat reflects
the wave back. The submarine crew receives the reflected waves 6 s after it was sent out. How far
is the boat from submarine​

Answer 1

Answer:

4500m

Explanation:

v- 1500m/s

t- 6s

D- ?

v = 2D/t

1500=2D/6

2D= 1500(6)

2D=9000m

D= 9000/2

D= 4500m

Answer 2

4500m

Explanation:

D=

s× t

2x= 1500×6

x= 4500
