9. SOLUTION: The speed of a stream is 5 mph. A boat travels 9 miles ...
= 14 mph. It is your answer: the speed of the boat in still water is 14 miles per hour.
You can put this solution on YOUR website! . The speed of a stream is 5 mph. A boat travels 9 miles upstream in the same time it takes to travel 19 miles downstream. What is the speed of the boat in still water? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Let u = the speed of the boat in still water. Then the speed of the boat relative the bank of the river is u-5 when it moves upstream, and u+5 when it moves downstream. We can write the basic equation for travel and distance problems Time = in the form t = (1) for moving upstream, and t = (2) for moving downstream. Since the left side, t, is the same in both equations, you get a single equation for u = . To solve it, multiply both sides by the product (u-5)*(u+5) and simplify: 9*(u+5) = 19*(u-5), 9u + 45 = 19u - 95, 45 + 95 = 19u - 9u, 10u = 140, u = = 14 mph. It is your answer: the speed of the boat in still water is 14 miles per hour.
FAQs
What is the speed of boat in still water if it can row 1 km downstream in 10 minutes and 1 km upstream in 20 minutes? ›
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? The speed of the boat in still water is 4.5 kmph.
What is the ratio of the speed of a boat upstream to the speed of current? ›Ratio of upstream speed to that of downstream speed is 3:5. If speed o... A boat take 6 hours to travel 36 km downstream and 24 km upstream.
What is the speed of the stream a person can draw a distance of 1 km upstream in 10 minutes and downstream in 4 minutes? ›A person can row a distance of one km upstream in ten minutes and downstream in four minutes. What is the speed of the stream ? Speed of the stream, y = (D - U)/2 = (15- 6)/2 = 9/2 = 4.5 km/hr.
What is the speed of a boat in still water if upstream speed is 22km h * R and downstream speed is 34km h * R ›If upstream speed is 22 km/hr and downstream speed is 34 km/hr, what is speed of boat in still water? If upstream speed is 22 km/hr and downstream speed is 34 km/hr, what i... The speed of a boat in still water is 9 km/hr.
How do you calculate the speed of a downstream boat? ›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.
How do you calculate the speed of a boat in still water? ›Boat's speed in still water = ½ (Downstream Speed + Upstream Speed) Downstream = (u+v)Km/hr. Boat's average speed = {(Upstream Speed x Upstream Speed)/Boat's Speed in Still Water} Stream's Speed = ½ (Downstream Speed – Upstream Speed)
What is the ratio between the speed of a boat upstream and downstream? ›The ratio between the speed of a boat upstream and downstream is in the ratio of 3 : 5.
What is the ratio of upstream and downstream? ›The ratio of the distance carried away by the water current, downstream, in crossing a river, by a person, making same angle with downstream and upstream is 2:1.
What is the speed of stream when a boat goes 12 km upstream in 48 minutes? ›12 km upstream in 48 min. ⇒ it will cover 15 km in 1 hr. Speed of stream = 2 km / hr. ∴ Speed of boat in still water = 15 + 2 = 17 km / hr.
What is the speed of the stream when a man goes 12 km upstream and 28 km downstream in 5 hours? ›A man rows upstream 12 km and downstream 28 km taking 5 hours each time. The velocity of water current is: 2 1 5 km/hr.
What is the rate of the stream if a boat covers 120 km? ›
Rate of downstream = distance / time = a = 120km / 4 hours = 30 km/hr. Since it takes same time to cover this 40km, Time taken in upstream = 4 hours. Rate of upstream = distance / time = b = 40km / 4 hours = 10 km/hr.
When a boat goes upstream for a distance of 24 km? ›When a boat goes upstream for a distance of 24km and downstream for 24km with a speed of 18 km/h, the time difference is 1 hours.
What is the speed of the upstream? ›The speed of the river with respect to the banks of the river is what we call the rate of the flow of the stream. This is what we denote with the letter 'r'. Therefore the speed upstream is (b – r) and the speed downstream is (b + r). Let us see a few solved examples and test these formulae.
What is the speed of boat in still water in 15 km hr and the rate current is 3km hr the distance travelled downstream in 12 minutes? ›The distance travelled downstream in 12 minutes will be? Speed downstream = (15 + 3) kmph = 18 kmph. km = 3.6 km.
What is the speed of the boat in still water if it goes 20 km downstream in 1 h and the same distance upstream in 2h? ›x=15 km/hr.
What is the speed of a boat in still water is 10 km hr if it can travel 26 km downstream? ›If it can travel 26 km downstream and 14 km upstream in the same time, the speed of the stream is : 2 km/hr b.
What is the speed of a boat in still water is 12 km hr and the rate of current is 4 km hr? ›Explanation: Speed downstream = (12 + 4) kmph = 16 kmph.
What is the speed of a boat in still water is 11 km it can go 12 km upstream? ›Speed of the stream = 5 km/hr. Q. The speed of a boat in still water is 11 km/hr. It can go 12 km upstream and return to the original points in 2 hours 45 min.
