Answer :
To answer this question, we need to find the distance traveled by the small submarine. We need to subtract the distances in this case. Then, we have:
[tex]d=-180-(-1320)=-180+1320=1140ft[/tex]Then, the small submarine traveled 1140 feet from -1320 feet to -180 feet.
If we need to know how fast the submarine must be, we need to divide the previous result by 60 minut
