Challenge! Ready? A boat in calm seas travels in a straight line and ends the trip 22 km west and 53 km north of its original position. To the nearest tenth of a degree, find the direction of the trip.

    So is it just the normal challenge or are you actually solving it this time?

    Assume the start is at (0,0) The end is at (-22,53). ---- direction = tan^-1(-53/22) = -67.46 But the angle is in the 2nd Quadrant. So, direction = -67.46 + 180 = 112.54 degrees. Is this right?

    arctan(53/22)=67.5° N 22.5° W, 22.5° west of north

    I got an angle of 22.5 degrees West of North, that would resolve to a bearing of 360-22.5 degrees or 337.5 degrees on a compass.

    Taking in consideration that North is 0 degrees, I say you got it right.

    Note that direction, North is 0 degrees and then you rotate clockwise, East is 90 degree, South is 180 degress etc.

    However, I would check with your instructor, what he wants

    22.5 West of North also describes it well.

    And it was right to this? http://assets.openstudy.com/updates/attachments/55b62750e4b0d48ca8eef4f1-lollygirl217-1438001228465-as.jpg

    That describes the absolute angle. But you are asked for "direction"

    Your response 22.5 degrees west of north, should be satisfactory.
