If you would like to know how far is Julian from his starting position, you can calculate this using the following steps:
First, you have to make a right triangle, where the hypotenuse of this triangle will actually be the distance we are looking for. The distances of the other two sides are 444 kilometers, and 777 kilometers - 222 kilometers; to be exact: 444 kilometers and 555 kilometers.
The distance we are interested in ... d: d^2 = 444^2 + 555^2 d^2 = 197136 + 308025 = 505161 d = sqrt(505161) d = <span>710.7 kilometers </span> The correct result would be <span>710.7 kilometers.</span>
