The answer is −10d4+17d2s−6s2
Answer:
The distance between the ships is changing at 42.720 kilometers per hour at 4:00 PM.
Step-by-step explanation:
Vectorially speaking, let assume that ship A is located at the origin and the relative distance of ship B with regard to ship A at noon is:
Where and are the distances of ships A and B with respect to origin.
By supposing that both ships are travelling at constant speed. The equations of absolute position are described below:
Then,
The rate of change of the distance between the ship is constructed by deriving the previous expression:
Its magnitude is determined by means of the Pythagorean Theorem:
The distance between the ships is changing at 42.720 kilometers per hour at 4:00 PM.
