Answer 2

$\huge\boxed{\fcolorbox{red}{yellow}{ANSWER..}}$

The Path of the Boat during its journey is in the form of a right triangle and the shortest distance is actually the Hypotenuse

Which has a Value = √[(50)²+(120)²] = 130Km.

Average Speed = Total distance travelled / Total Time.

= ( 50 + 120 + 130 ) / 3

= 300 / 3

= 100Km / Hr.
