Answer: 75 miles
Step-by-step explanation: This can be calculated using Pythagorean Therorem
Using a compass or brain memorization (Never eat soggy waffles, NESW) we can visualize that this will turn into a right triangle and we need to figure out the hypotenuse because that's the return distance and line back to the start
45^2+60^2=C^2
C^2 = 45^2 + 60^2
C^2 = 2025 + 3600
C^2 = 5625
Take the root of BOTH SIDES
C = √5625
C=75
