What will be speed of stream, if speed of boat in still water is 45km/hr?
A. The time taken by boat to cover 240 km upstream is 4 hours more than time taken by boat to cover same distance in downstream.
B. Boat takes total 15 hours to cover 300 km in downstream and upstream.

Options

A. Statement A alone is sufficient to answer the question but statement B alone is not sufficient to answer the questions.
B. Statement B alone is sufficient to answer the question but statement A alone is not sufficient to answer the question.
C. Both the statements taken together are necessary to answer the questions, but neither of the statements alone is sufficient to answer the question.
D. Either stetement A or stetement B by itself is sufficient to answer the question.

Explanation

To determine the speed of the stream given the speed of the boat in still water is 45 km/hr, we will analyze the two statements provided.

### Given:
- Speed of the boat in still water (B) = 45 km/hr
- Let the speed of the stream (S) be unknown.

### Statement A:
The time taken by the boat to cover 240 km upstream is 4 hours more than the time taken to cover the same distance downstream.
