A submarine is at a depth of 2 1/3km below the sea level and if it starts ascending at the rate of 800m/her then find its position after two hours?

the depth of the submarine = 2 1/3 km = 7/3 km.

speed of the submarine = 800 m/hr 

therefore distance covered in 2 hr = 800*2 =1600 m. = 1.6 km

therefore the depth of the submarine =

thus the depth of the submarine is 11/15 km.

hope this helps you.

cheers!!
