Answer 2

$\huge\sf\fbox{\underline\red{Answer}~:-}$

$\fbox\purple{Given~:}$

The deepest part of the ocean in the world is the Mariana Trench in the Pacific Ocean.

It is 11000 m deep.

$\fbox\orange{To~Find~:}$

How long will it take for sound transmitted by a ship from above the surface of water above the trench to be reflected ?

$\fbox\green{Solution~:}$

• Depth of ocean = 11,000 m

• Speed of sound in water = 1500 m/sec.

•°• $Speed = \frac{Distance}{Time}$

•°• $Time = \frac{Distance}{Speed}$

$:•⟹\frac{2 \times 11000m}{1500 \frac{m}{sec.} }$

$:•⟹ Time =\frac{22000sec.}{1500} = 14.66sec.$
