Answer:
232°
Step-by-step explanation:
There are a couple of ways to find the desired direction. Perhaps the most straightforward is to add up the coordinates of the travel vectors.
30∠270° +50∠210° = 30(cos(270°), sin(270°)) +50(cos(210°), sin(210°))
= (0, -30) +(-43.301, -25) = (-43.301, -55)
Then the angle from port is ...
arctan(-55/-43.301) ≈ 231.79° . . . . . . . 3rd quadrant angle
The bearing of the ship from port is about 232°.

<em>Comment on the problem statement</em>
The term "knot" is conventionally used to indicate a measure of speed (nautical mile per hour), not distance. It is derived from the use of a knotted rope to estimate speed. Knots on the rope were typically 47 ft 3 inches apart. As a measure of distance 30 knots is about 1417.5 feet.
Answer:
The % Alicia speed walking is 125 % of average walking
Step-by-step explanation:
Given as :
Distance cover by Alicia while walking = 4 miles
Time taken = 1 hour
So, Speed of Alicia while walking =
Or, S 1 =
I.e S 1 = 4 mph
And
Distance cover by Alicia while speed walk = 5 miles
Time Taken = 1 hour
So, Speed of Alicia while speed walking =
Or, S 2 =
I.e S 2 = 5 mph
Or, % Rate = ×100 = 125
Hence The % Alicia speed walking is 125 % of average walking Answer
