<PRE><B>Question 746429</B>
An airplane flies from City A in a straight line to City B, which is 130 kilometers north and 195 kilometers west of City A. How far does the plane fly?
----
The route line is the hypotenuse of a right triangle with
sides equal to 130 and 195 km.
--------
Use Pythatoras to solve for the route length.
route = sqrt[130^2+195^2] = 234.36 km

Cheers,
Stan H.
