The speed of a boat along the stream is 8 km/h and against the stream is 6 km/hr. The time taken by the boat to sail 28 km in still water is
Speed of a boat is 25 km per hour in still water and the speed of the stream is 5 km per hour. If the boat takes 15 hrs to go to a place and come back, the distance of the place is
Two boats A and B start towards each other from two places, 150 km apart. Speed of the boat A and B in still water are 16 km/hr and 14 km/hr respectively. If A proceeds down and B up the stream, they will meet after.
A man can row at a speed of 15/2 km/hr in still water. If he takes 4 times as long to row a distance upstream as to row the same distance downstream, then the speed of stream (in km/hr) is
A man can row 6 km/h in still water. If the speed of the current is 2 km/h, it takes 3 hrs more in upstream than in the downstream for the same distance. The distance is
A man rows 8 km/h in still water. If the river is running at 2 km/h, it takes 32 min to row to a place and back. How far is the place?
A person can row 7 1/2 km an hour in still water and he finds that it takes him twice as long to row up as to row down the river. The speed of the stream is:
A man can swim 3 km/hr in still water. If the velocity of the stream is 2 km/hr, the time taken by him to swim to a place 10 km upstream and back is:
If downstream speed of a boat is 16 kmph and its upstream speed is 11 kmph, what is the speed of stream?
