Ответ:
The correct option is B.
Step-by-step explanation:
Solution:
The shortest on map is 7cm
The longest on map is 14 cm
The shortest in real life is 120 km
Let the longest in real life is x km
So,
The ratio is:
7/120 = 14/x
x = 120*(14) / 7
x=1,680/7
x= 240 km
The longest in real-life is 240 km
Thus the correct option is B
