Answer:
Step-by-step explanation:-
After five minutes it's position of submarine is
1min=50km
In 5min= 50×5= 250km
Position of submarine = -1200+205= -995km
If position of submarine = -500
So the position of the submarine 6min ago will be :-
1min=50km
6min=6×50=300km
Position of submarine=-500-300= -800km
