Question 1141318: Ezra rides his bike from home at point H(-1,2) to school at point S(2,2), to the comic book store at point C(2,-2) and then back home again. If each unit represents 2 miles, what is the total distance Ezra rode? Answer by greenestamps(13203) (Show Source):
When graphed, the first two parts of the trip are horizontal and vertical, so it is easy to determine their lengths.
Those two lengths are then the legs of a right triangle, making it easy to find the length of the third part of the trip (the hypotenuse of the right triangle).
Now you know the total distance; multiply that by the 2 miles per unit to get the total distance.
