What can Row 1 km with stream in 10 minutes and 1 km against the stream in 20 minutes the speed of the boat in still water is?
Answer: 0.075 km / min. or 4.5 km/hour.
How long will it take to row 20 km upstream if one can row 10 km in 10 minutes in still water and the same distance in 8 minutes with the stream?
Time requires to travel 20 km upstream is 26.67 min . One can row 10 km in 10 minutes in still water . The same distance in 8 minutes with the stream . Let , speed of stream be u and speed of boat is v .
What is the speed of the boat in still water 1 The boat covers a distance of 140 km in 7 hours upstream 2 The boat covers the same distance in 5 hours downstream?
I. Speed of boat in still water is 8 km/hr.
What is boat and stream?
1) Still water: The water of a river or any other water body which is not flowing is known as still water. 2) Stream: It is the flowing water of a river which is moving at a certain speed. 4) Downstream: The boat or a swimmer moving along the stream is known as moving downstream i.e. along the flow of water.
What is the speed of the stream if a boat travels?
Speed of stream = 2 km / hr. ∴ Speed of boat in still water = 15 + 2 = 17 km / hr. Q8. A motorboat can travel at 5 km/hr in still water.
What is speed of the stream?
And, the direction against the stream is called upstream. If the speed of a boat in still water is u km/hr and the speed of the stream is v km/hr, then: Speed downstream = (u + v) km/hr. Speed upstream = (u – v) km/hr….Exercise :: Boats and Streams – Important Formulas.

How long does it take a boat to row 1 km?
A boat can row 1 km with stream in 10 minutes and 1 km against stream in 20 minutes. What is the speed of the boat in still water? – Quora A boat can row 1 km with stream in 10 minutes and 1 km against stream in 20 minutes. What is the speed of the boat in still water?
How long does it take to row 1 km with stream?
See what the community says and unlock a badge. Given : A boat can row 1 km with stream in 10 minutes and 1 km against stream in 20 minutes. To find : What is the speed of the boat in still water?
What will be the speed of the boat in 1 hour?
In one hour, a boat goes 13 km/hr in the direction of the stream and 7 km/hr against the direction of the stream. What will be the speed of the boat in still water? Q 3. A woman can row upstream at 16 km/hr and downstream at 26 km/hr.
How do you calculate the speed of a boat in water?
Speed of the stream = ½ (Downstream Speed – Upstream Speed) Speed of the stream = ½ (26-16) = ½ × 10 = 5 km/hr Q 4. A speedboat, whose speed in 15 km/hr in still water goes 30 km downstream and comes back in a total of 4 hours 30 minutes.
