Direction: Some data about the boat is given below. Analyze the conditions and answer the following questions:

The direction of the stream is alternating starting from Monday where the direction of the stream is estimated to be along the direction of the boat. The speed of the stream can be either 5 kmph or 10 kmph for two consecutive days starting from Monday because of which the boat rower adjusts the speed of the boat to 45 kmph and 30 kmph respectively. After every 4 hours the boat is turned off for 30 minutes and after every 6 hours the rover stops the boat at a station for refueling for 30 minutes. Assume when the boat is turned off, the boat moves in the direction of the stream and the boat is stationary during the time of refueling.
