Answer:
Step-by-step explanation:
400^2 = 160,000
5 2/6 = 32/6 = 16/3
6 70/30 = 250/30 = 25/3
16/3 * 25/3 = 400/9
400/9 / 160,000 = 1/3600
E+1.2=2 So what does is E?

Answer:
1.5 nautical miles
Step-by-step explanation:
See the attached diagram.
The submarine starts to dive at point A and diving along AB.
If the distance traveled underwater i.e. AB = 1.7 Nautical miles and C is the point directly above its current position at B.
Then Δ ABC is a right triangle having ∠ BAC = 28° {Given}
So, using trigonometry we can write
⇒ nautical miles.
Therefore, the surface distance that the submarine travels is 1.5 nautical miles. (Answer)
