Aptitude Questions Boats and Streams.

A boat moves upstream. If the speed of the water is 15 kmh then the speed ofthe boat in still water is. A boat moves downstream at the rate of 1 km in 6 min and upstream at the rate of 1 km in 10 min The speed of the current kmhr is. Determine the speed of the stream and that of the boat in still water.

If the speed of the stream is 4 kmhr find the time taken by the boat to go. While going down stream the water current km hr gets added to boats speed and opposite when boat goes upstream ie boats speed is reduced by an amount of water current acting in opposite direction. Times of the two trips are equal.

A boat covers 24 miles upstream and 36 miles downstream in 6 hours while it covers 36 miles upstream and 24 miles down stream in 65 hours. Thats 3 hours and 52 minutes and 30 seconds. 1 15 2 60 kmph 2 60 15 kmph 8 kmph.

If the speed downstream is a kmhr and the speed upstream is b kmhr then. A boat goes 30 km upstream and 44 km downstream in 10 hours Video Example 19A boat goes 30 km upstream and 44 km downstream in 10 hours. Let the speed of a boat in still water x kmhrand speed of the stream y kmhr Speed of a boat in upstream x - y kmhr andSpeed of a boat in downstream x y kmhrWe know thatTime Distance SpeedAccording to the conditions in the question we get.

Upstream If the boat is flowing in the opposite direction to the stream it is called upstream. Rate downstream of boat 5 kmph. Boat moves 9 kilometers upstream in the same amount of time it moves 19 kilometers downstream.

A man can row a boat at 10 kmph in still water and the speed of the stream is 8 kmph. A 1 kmph b2 kmph c3 kmph d25 kmph. A Boat Moves 10 Kilometers Upstream In The Same Amount Of Time It Moves 15 Kilometers Downstream.
