about 0.81 miles
Step-by-step explanation:
Alyssa's route can be considered a right triangle with legs of length 19 and 28 (hundredths). The Pythagorean theorem tells us the hypotenuse (x) will satisfy ...
x^2 = 19^2 +28^2
x^2 = 1145
x = √1145 ≈ 34 . . . . hundredths of a mile
Then Alyssa's total route is ...
0.19 + 0.28 + 0.34 = 0.81 . . . . miles
