Answer:

  • See below

Step-by-step explanation:

a)

i)

<u>Use the law of cosines:</u>

  • AB=\sqrt{PA^2+PB^2-2*PA*PB*cosP}
  • AB=\sqrt{60^2+100^2-2*60*100*cos80} =\sqrt{11516.22} =107.31

ii)

<u>Use the law of sines:</u>

  • sin ∠A / PB = sin ∠P / AB
  • sin ∠A / 100 = sin 80 / 107.31
  • sin ∠A = 100 sin 80 deg / 107.31
  • sin ∠A = 0.92
  • ∠A = arcsin 0.92
  • ∠A = 67° (rounded)

iii)

<u>Bearing of B from A:</u>

  • 90° + (67° - 30°) =
  • 127°

b)

<u>PB is longer distance. Time to reach B:</u>

  • t = d/s
  • t = 100/20 = 5 hours

<u>The speed s of the slower ship:</u>

  • s = d/t
  • s = 60/5 = 12 km/h
