Answer:
44 km
Step-by-step explanation:
Let's find x using the Pythagorean theorem.
a^2 + b^2 = c^2
x^2 + 165^2 = 173^2
x^2 = 173^2 - 165^2
x^2 = 29,929 - 27,225
x = sqrt(2704)
x = 52
Indianapolis to Lima: 173 km
Indianapolis to Dayton then to Lima = 165 km + 52 km = 217 km
Difference: 217 km - 173 km = 44 km
Answer: 44 km
