Answer:

The longest of the real-life distances is 238.125 km....

Explanation:

The shortest side of triangle is 8cm

The longest side = 15cm

Now set up a proportion:

8/127 = 15/x

By cross multiplication we get,

8*x = 15*127

8x = 1,905

Divide both sides by 8

8x = 1,905/8

x = 238.125 km

The longest of the real-life distances is 238.125 km....
