    Bearings Problem - cannot solve it!

    Plane A flies a distance of 220 miles in the direction N20(degrees)E.
    Plane B departs from the same airport and flies a distance of 365 miles in the direction S55(degrees)W.

    Calculate the distance between the two planes.

    Any help would be much appreciated!!!
    Thank you!!

    You need to determine the co-ordinates of the planes.

    Draw a picture, and then create two right angled triangles. Using these triangles, you can use the RAT trigonometric ratios to determine how far North/South and East/West from the origin they are.

    Then use the distance formula (Pythagoras) to determine how far away they are from each other.

    Does that make sense or do you want me to explain further?
