Answer:
18 miles east; 24 mph east
Explanation:
In order to find how far east of Wilmington is the ship after 1 hour, we just need to substitute t = 1 into the formula of the position.
The equation of the position is
where t is the time. Substituting t = 1,
So, the ship is 18 miles east of Wilmington.
To find the velocity of the boat, we just need to calculate the derivative of the position, so
And by substituting t = 1, we find the velocity after 1 hour:
And the direction is east.
