The map shows the location of the airport and a warehouse in a city. Though not displayed on the map, there is also a factory 112 miles due north of the warehouse. Coordinate grid shown from negative 84 to positive 84 on x axis at intervals of 14 and negative 84 to positive 84 on y axis at intervals of 14. A straight line is shown between points labeled Airport and Warehouse. Airport is the ordered pair negative 42, 56, and Warehouse is the ordered pair 42 and negative 56. A signage showing directions North, South, East, and West is shown in the empty quadrant on the graph. A truck traveled from the warehouse to the airport and then to the factory. What is the total number of miles the truck traveled? 112 154 224 252

224 miles OK. The total distance traveled is the sum of two smaller trips. Let's calculate their distances independently. Warehouse to Airport (42, -56) to (-42, 56) Using the Pythagorean theorem d = sqrt((42 - -42)^2 + (-56 - 56)^2) d = sqrt(84^2 + (-112)^2) d = sqrt(7056 + 12544) d = sqrt(19600) d = 140 Airport to Factory (-42, 56) to (42, -56+112) (-42, 56) to (42, 56) Using the Pythagorean theorem again. d = sqrt((-42 - 42)^2 + (56 - 56)^2) d = sqrt((-84)^2 + 0^2) d = sqrt(7056 + 0) d = sqrt(7056) d = 84 So the truck traveled 140 + 84 = 224 miles.
