Relative velocity

[Clari]

Ship A travels at 3m/s due NE, ship B travels at 2.6 m/s in direction S30E.
a. What are the magnitude and direction of the velocity of ship A relative to ship B?
b. After what time will they be 140m apart?

I have found the answer to be 4.45m/s
But I don't know whether it is true...and I am not sure of its direction.
Please help. :frown:

you can use the components of that vector you figured out to get the direction.
