The question, in short

Using a scale drawing where 1 cm represents 20 km, find the bearing of S from P, then find the time for S to sail directly to P at 24 km/h, to the nearest hour.

Summarised in our own words. Use the official paper for the exact wording and the diagram.

Part (a) · 1 mark

Find the bearing of S from P from the scale drawing.

  1. 1Measure angle clockwise from north at P to S
  2. 2Obtain 308−312
  3. 3Answer is 310

Answer310 (accept 308 to 312)

Part (b) · 4 marks

Ship S sails directly to P at 24 km/h. Work out the journey time to the nearest hour.

  1. 1Measure distance from S to P on diagram: 8.3 − 8.7 cm
  2. 2Scale: 1 cm = 20 km, so distance = 8.5 × 20 = 170 km
  3. 3Speed = 24 km/h
  4. 4Time = distance ÷ speed = 170 ÷ 24
  5. 5170 ÷ 24 = 7.08...
  6. 6Round to nearest hour: 7
