Use the map shown below to find the distance between cities A and B to the nearest tenth

Question

A=(0,0)

B=(7,3)

Answer 1

distance between 2 points (x1,y1) and (x2,y2) is

sqrt((x2-x1)^2+(y2-y1)^2)

so for out problem where (x1,y1) = (0,0) and (x2,y2) = (7,3):

distance = sqrt((7-0)^2 + (3-0)^2) = 7.6
