Arithmetic Aptitude :: Boats and Streams
- A person can swim in still water at 4 km/h. If the speed of water 2 km/h, how many hours will the man take to swim back against the current for 6km?
- A boat goes 100 km downstream in 10 hours, and 75 m upstream in 15 hours. The speed of the stream is?
- A man can row his boat with the stream at 6 km/h and against the stream in 4 km/h. The man's rate is?
- A man can swim in still water at 4.5 km/h, but takes twice as long to swim upstream than downstream. The speed of the stream is?
- A man can row with a speed of 15 kmph in still water. If the stream flows at 5 kmph, then the speed in downstream is?
- A man can row upstream at 25 kmph and downstream at 35 kmph, and then find the speed of the man in still water?
- A boat can move upstream at 25 kmph and downstream at 35 kmph, then the speed of the current is?
- A man swims downstream 30 km and upstream 18 km taking 3 hours each time, what is the speed of the man in still water?
- A man swims downstream 72 km and upstream 45 km taking 9 hours each time; what is the speed of the current?
- A man can row 6 kmph in still water. When the river is running at 1.2 kmph, it takes him 1 hour to row to a place and black. How far is the place?
