Aship leaves a port p and travels 30 km due north . then it changes course and travels 20 km in a direction 30° east of north to reach port r. calculate the distance from p to r.

The distance between P and R is equal to the net displacement of the ship in going from port P to port R

Vector P = 30 km North

Vector R = 20 km 30° east of north

Now, the angle between Vector P and vector R = 90° + 30 ° = 120°

Using the formula to find the addition of two vectors:

Resultant =

Plugging the values:

Resultant = 26.457 Km

The distance from P to R is 26.457 km

hèllo, sorry i really need some more points so if you need this qustion answered than retype it

d is the correct answer
