Question

A bakery needs to supply bread to every store within a six-kilometer radíus.
How many centimeters will this radíus be when drawn on the map? Hint:
convert 6 km to cm, and then multiply by the representative fraction: 1/25,000.

Answer 1

The 6km supply Radius will have a length of 24 cm on a map

• Supply Radius = 6 km

Convert to cm ; which is the unit of representative fraction

• 1 km = 100000 cm
• 6km =?
• Cross multiply :
• 6km = 600,000 cm

• The reprentative fraction = 1 / 25000
• The representative fraction can be interpreted to mean ; 1 cm on the map represents 25000 cm on ground.

• Length of the Radius on the map = (1 / 25,000 × 600,000) = 24 cm

Therefore, the 6 km Radius will have a length of 24 cm on the map.
