Solve the given parts of following question:

Question: Mary needs to row her boat across a 60m wide river that is flowing to the east at a speed of 1.0 m/s. Mary can row the boat with a speed of 2.0 m/s relative to the water.

Part I: If Mary rows straight north, how far downstream will she land?

Part II: Draw a picture showing Mary's displacement due to rowing, her displacement due to the river's motion, and her net displacement.

I need tutor help to solve the above question.
