Answer: -231 ft

Step-by-step explanation:

The submarine started at sea level = 0

It submerged 140 ft = -140 ft

It traveled 40 miles horizontally so it is still at -140 ft

It dove down an additional 120 ft = -260 ft (-140 + -120)

It traveled 25 miles horizontally so it is still at -260 ft

It rose 29 ft = -231 ft (-260 + 29)

Note: submerged and dove are negative values and rose is positive

0 - 140 - 120 + 29 = -231

Seal level would be 0.

It then submerged 140 feet so it is at -140

It then dove 120 more feet so it is now at - 260 feet.

It rose 29 feet

It is now at -231 feet. ( 231 feet below sea level)
