Question

A family is driving from Phoenix to San Francisco. On a map grid, Phoenix is located at (–12, –16), and San Francisco is located at (–36, 5). Along the trip, the family stops in Blythe, located at (–20, –9), and Los Angeles, located at (–33, –4) on the map. Find the total distance of the trip.

Answer 1

assuming that you are traveling on a perfect grid

the distance from phoenix to blythe is
\[(20-12) + (16-9)\]

blythe to LA is \[(33-20) + (9-4)\]

and LA to San Francisco is \[(36-33)+(5+4)\]

you get those numbers from summing the x distance and y distance, understand how i got those numbers?
