Atriangle drawn on a map has sides that measure 7 cm, 14 cm, and 12 cm. the shortest of the corresponding real-life distances is 120 km. find the longest of the real-life distances.
a. 195.7 km
b. 240.0 km
c. 250.0 km
d. 205.7 km

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
