See the picture please

To do this problem, we must to find the hypotenuse of a right triangle where one cathetus is 444 km and the other one is the sum of 111 and 555km.

them the pythagorean theorem says c² = a² + b²

c² = 444² + (111+555)²

c² = 444² + 666²

c² = 197136 + 443556

c² = 640692

c = 800.4 km
