Two locations, C and D, are marked on the map. The bearing from C to D is 047°. Work out the straight-line distance between C and D. Give your answer to 3 s.f.

Step 1: Measure the straight-line distance between points C and D on the map using a ruler. Measured map distance = 3.8 cm Step 2: The map scale is 1 cm → 3 km. Actual distance d = map distance × 3 km/cm; d = 3.8 × 3 = 11.4 km Step 3: Give the answer to 3 significant figures. 11.4 has 3 significant figures and includes units. 11.4 km 11.4 km

Measure the straight-line distance between points C and D on the map using a ruler.
Measured map distance = 3.8 cm
The map scale is $1 \;\mathrm{cm} \to 3 \;\mathrm{km}$ .
Actual distance $d =$ map distance $\times 3 \;\mathrm{km/cm}$
$d = 3.8 \times 3 = 11.4 \;\mathrm{km}$
Give the answer to 3 significant figures.
11.4 has 3 significant figures and includes units.
