Answer: The new depth of submarines would be -195 meters, i.e. 195 meters below the sea level.

Explanation:

Since we have given that

Depth of submarine = 250 meters below sea level. = (-) 250 meters

Rises by = 75 meters = (+) 75 meters

Dives by = 20 meters = (-) 20 meters

So, the new depth would be

$-250+75-20\\\\=-195\ meters$

Hence, the new depth of submarines would be -195 meters, i.e. 195 meters below the sea level.
