Problema Solution
A map has a scale of 1 cm : 11.5 km. Two cities are 5.5 cm apart on the map. To the nearest tenth of a kilometer, what is the actual distance corresponding to the map distance?
Answer provided by our tutors
1 cm on the map means 11.5 km in real
5.5 cm on the map means x km in real
1: 11.5 = 5.5 : x
x = (11.5*5.5)/1
x = 63.25 km
x = 63.3 km to the nearest tenth of km
the actual distance between the cities is 63.3 km to the nearest tenth of km.
