A motorboat traveling with the current can go 30 miles in 2 hrs. Against the current , it takes 3 hrs. to go the same distance. Find the rate of the motorboat in calm water and the rate of the current!

My set up:

Let x = speed of motorboat in still water

Let y = speed of current

See attachmentfor table I created.

From the table, I created the following system of equations but got the wrong answers.

2x + 2y = 30

3x - 3y = 30

What did I do wrong?
