Euclidean distance

Calculate the Euclidean distance between shops A, B, and C, where:
A 45 0.05
B 60 0.05
C 52 0.09

The first figure is the weight in grams of bread, and the second figure is the USD price.

Correct answer:

|AB| =  15
|BC| =  8.0001
|AC| =  7.00011

Step-by-step explanation:

$|AB|=\sqrt{(45-60{)}^2+(0.05-0.05{)}^2}\doteq 15$

$|BC|=\sqrt{(60-52{)}^2+(0.05-0.09{)}^2}\doteq 8.0001$

$|AC|=\sqrt{(45-52{)}^2+(0.05-0.09{)}^2}\doteq 7.00011$
