1. A ship P sails at a steady speed of 45 km/h in
a direction of W 32◦ N (i.e. a bearing of 302◦)
from a port. At the same time another ship Q
leaves the port at a steady speed of 35 km/h
in a direction N 15◦ E (i.e. a bearing of 015◦).
Determine their distance apart after 4 hours

Answer:
193 KM
Step-by-step explanation:
After 4 hours, ship P has sailed 180 km, and ship Q 140 km.
Let O be the port of origin.
angle POQ = 58° + 15° = 73°
OP = 180 km
OQ = 140 km
The required distance is PQ.
PQ² = OP² + OQ² - 2(OP)(OQ)cos(POQ)
PQ² = 180² + 140² - 2(180)(140)cos(73°)
PQ² ≈ 37264
PQ ≈ 193 km
