Answer:
1 cm : 40 km.
Step-by-step explanation:
We are asked to find the scale factor of a map, when 3 cm on the map correspond to 120 km in the actual distance.
To find scale of the map, we will divide actual distance by distance on map as:
Since 1 cm on map corresponds to 40 km in the actual distance, therefore, the scale is 1 cm : 40 km.

Answer:
The smallest positive integer solution to the given system of congruences is 30.
Step-by-step explanation:
The given system of congruences is
where, m and n are positive integers.
It means, if the number divided by 5, then remainder is 0 and if the same number is divided by 11, then the remainder is 8. It can be defined as
Now, we can say that m>n because m and n are positive integers.
For n=1,
19 is not divisible by 5 so m is not an integer for n=1.
For n=2,
The value of m is 6 and the value of n is 2. So the smallest positive integer solution to the given system of congruences is
Therefore the smallest positive integer solution to the given system of congruences is 30.
