a boat travels north across a river at a velocity of 22meters/second with respect to the water the rivers velocity is 2,2 meters/second to the east what is the resultant velocity of the boat as measured from the land

22.11 m/s [ E 84.29º N]

Explanation:

Draw a vector diagram to get a vector of length 2.2 pointing to the right and a vector of 22 pointing to the top. Use the pythagorean theorem to find the length of the result of adding the two vectors (the resultant) as

then find the direction with an inverst tangent function:

the final answer is 22.11 m/s [ E 84.29º N]
