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.
