Calculate 55981

Calculate the following example:
On a map with a scale of 1:50,000, two places, A and B, are 4 cm apart. Find out:
a) what is the distance between these places in reality;
b) what is the scale of the map in which these places are 12 cm apart?

Correct answer:

x =  2 km
M2 =  3:50000

Step-by-step explanation:

M=50000 x1=4 cm km=4:100000  km=4.0105 km  x=M x1=50000 4105=2 km
x2=12 cm km=12:100000  km=0.00012 km  M2=x2/x=0.0001/20.0001=3:50000
