The map below shows a proposed road network linking four villages – D, E, F and G – in a rural district. The map scale is 1 cm : 0.5 km (i.e., 1 cm represents 0.5 km). The road segments are measured on the map as follows: DE = 3 cm, EF = 4.5 cm, FG = 2 cm and GD = 5 cm, forming a closed loop.

Question Parts

( a )
Calculate the total length of the road network on the ground in kilometres, giving your answer to two decimal places.
( b )
If a vehicle travels the entire loop at a constant speed of 60 km h⁻¹, estimate the travel time in minutes, rounded to one decimal place.
( c )
Discuss how a 5 % error in the map scale would affect the estimated total distance and travel time. Consider both an over‑estimation and an under‑estimation of the scale.
