The scale on a map is 2.5 cm : 12km. If a street is 6 cm long on the map, what is the actual length of the street?

30 km

Step-by-step explanation:

Converting measurements on a map

We saw above that if a map has a scale of 1 : 50000, then 1 cm on the map is 50000 cm in real life.

(a) Imagine we have measured a distance as 3 cm on this map, and we want to find out how far this is in real life.

To work out the distance in real life, we need to multiply this length by 50000.

This gives 3 cm × 50000 = 150000 cm which is 1500 m or 1.5 km.

Alternatively, we could have just remembered that each 1 cm on the map is 0.5 km in real life.

Hence, 3 cm on the map must be 3 × 0.5 km = 1.5 km in real life.
