Question

A triangle 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

Answer 1

The correct option is B.

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....
