Cincinnati

A map is placed on a coordinate grid. Cincinnati located at (5,4) and San Diego is located at (-10, -3). How far apart is Cincinnati from San Diego on the map? Round to the nearest tenth.

Result

d =  16.553

Solution:

d2=Δx2+Δy2  d=(5−(−10))2+(4−(−3))2=274≐16.5529≐16.553d^2=\Delta x^2+ \Delta y^2 \ \\ \ \\ d=\sqrt{ (5-(-10))^{ 2 } + (4-(-3))^{ 2 } }=\sqrt{ 274 } \doteq 16.5529 \doteq 16.553
