    Flying ButterFly---URGENT

    1. The problem statement, all variables and given/known data
    Monarch butterflies can sustain air speeds of 4.4 m/s while migrating. A certain monarch wants to fly to a location due west 4.7 km away. A steady 2.4 m/s breeze is blowing from the east to the west. How long will it take the monarch to make the trip to the location to the west?

    If all conditions stay the same, how long would it take the monarch to make the return trip?

    What is the total round trip flying time for the monarch? That is, how long would it take the butterfly to go to the west location, turn around, and come back?

    What would the total round trip time be, if no wind was blowing?

    2. Relevant equations

    i dont know how to start solving the problem

    3. The attempt at a solution

    i dont know how to start solving the problem.....

    its vectors quesitons...
    draw a diagram out and label it this will give you a good start.
    then its about adding vectors and using newtons law of motion

    Well you need to start somewhere...
    Break up the trip into outbound and return flight.
    With the breeze, will it take more or less time for the insect on the outbound trip compared to without a breeze?

    Looks like one dimensional motion to me.

    first thing to realize that the wind velocity completely adds (or subtracts), so when aloft it is already moving at 2.4m/s. Add the velocitys carefully as determined by the direction. Then time=distance/speed. see what you can do.
