A ship sets sail from Rotterdam, The Netherlands,
heading due north at 7.00 m/s relative to the water. The local
ocean current is 1.50 m/s in a direction 40.0º north of east.
What is the velocity of the ship relative to the Earth?

The Attempt at a Solution
I tried using the equation above but i noticed i needed to get a direction and that is where i am stuck.
The formula for calculating velocity is velocity = distance / time. This means that to find the velocity of the ship relative to earth, we need to know the distance the ship has traveled and the time it took to travel that distance.
The distance traveled by the ship can be determined by using a variety of methods, such as GPS tracking or measuring the distance between two points using known landmarks. The method chosen will depend on the accuracy and availability of data.
Yes, the velocity of the ship can be negative. This would indicate that the ship is traveling in the opposite direction of the reference point, in this case, the earth.
Time can be measured in a variety of units, such as seconds, minutes, or hours. The important thing is to ensure that the distance and time units are consistent in the calculation.
Several factors can affect the accuracy of the calculated velocity, including measurement errors, external forces acting on the ship, and changes in speed or direction during the measurement period. It is important to minimize these factors as much as possible to obtain a more accurate velocity measurement.
