Protecting the fleet Parts C. & D. (Posted on 2015-12-15) Difficulty: 3 of 5
A fleet of ships is on a straight course at a speed of one knot. It is guarded by a cruiser that travels at two knots.

C. The fleet is in a straight line one nautical mile long but is not single file. Instead the motion is at an angle of θ from being abreast. The cruiser starts at one end and continuously motors to the other and back again. How long does one cycle take?

D. The fleet is in an equilateral triangle formation, one nautical mile on a side. The cruiser hems close to the sides as it cycles around this triangle. How long does one cycle take if:
i. One side of this triangle is perpendicular to the direction of travel?
ii. One side of this triangle is parallel to the direction of travel?

Try to give exact answers.
