Step-by-step explanation:

Horizontal displacement = 100 km

Position with respect to sea level = -1.4km

Step-by-step explanation:

Lets take the displacement downwards to be negative displacement and displacement upwards to be positive.

The horizontal distance from the shore remains constant whereas the displacement from the sea level varies as the submarine moves.

The upward displacement = 3/5 km

Downward displacement = - 11/10 km and - 9/10 km

Total displacement = 3/5km - 11/10 km - 9/10km = - 7/5 km = - 1.4 km

Horizontal distance from the shore = 100km
