Homework Statement
helicopter is flying in air it goes A,B,C,D points
which are distributed in square
and helicopter goes one circle in 4 hours
if wind is blowing in direction from A to D
then the whole circle is flown in 3 hours
question: how does it takes to fly from A to C if wind blows in the same direction
Homework Equations
The Attempt at a Solution
if the whole circle needs four hours without wind then to go one section of square needs 1 hour
and let's call the length of one section x and the same will be velocity x km/hour
lets call velocity of wind y
see the graph in the file attached
