## 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
