He is a student in college. I doubt that he is an EE student.

If the information that you provided is the only information that you were given, then you have to make assumptions to clarify the problem. Your assumptions may be wrong. This is the usually case with many new problems. You ask questions of the originator of the problem, or you experiment with the device or whatever, and use new information, or experimental data to modify your assumptions. Then proceed to the next step, and this process may need to be repeated many times.
Note that many of the previous responses have posed some assumptions or questions for you to answer.
If this is simply a class problem and there is no other information, then state your assumptions, and show how you would go from those assumptions to an answer that you produce from the assumptions.
I had a final exam once where the regular teacher was not present, and the head of the department, William G. Dow, was the substitute. There was one question that appeared to have a mistake in the question. The question lacked consistency. All our exams were on the honor system, most were open book, and typically the teacher was not in the room, but rather in their office. I went to Dow's office and indicated the problem with the question. His response was --- describe how I thought the question should have been written and answer based on my assumptions. You would have to know Dow to know his teaching techniques, But his response made perfect sense.
In a teaching environment Dow tried to make his students think, rather than just answer a question. In a non-teaching environment at the Electronics Defense Group, a part of the Electrical Engineering Department, where I worked while I was a student, Dow would ask questions in program review meetings of the presenter that others might want to, but were afraid to, to try to get the presenter to clarify what they had said. He was still teaching.
