Answer 2

Answer: -140 m

Step-by-step explanation: A submarine move at the speed of -20 m per minute that means it submerge 20 m below sea in 1 min.

speed= -20 m/min

time= 7 minutes.

distance= speed x time

distance submerged is -140 m.

so its 140 m below sea level. or 140 m away from the water surface.
