Boat Upstream & Downstream - Tips, Tricks, Formula & Sample Questions
It travels 49 mi upstream and 49 mi downstream in a total time of hr. What is the speed of the current? In every example I can find of this type of problem, the respective times traveled upstream and downstream are given, but not the distance. Here we have the distance traveled upstream and the distance traveled downstream, and the cumulative time traveled overall, but not the times traveled upstream and downstream. How do I go about finding the speed of the river current given these data points? linear-algebra. He travels a certain distance downstream in 1 hour and come back in 11?2 hour. i.e., distance travelled downstream in 1 hour = distance travelled upstream in 11?2 hour. Since distance = speed ? time, we have $(x + 3) ?1 = (x - 3)\dfrac{3}{2}\\~\\\Rightarrow 2(x + 3) = 3(x-3)\\~\\\Rightarrow 2x + 6 = 3x - 9\\~\\\Rightarrow x = 6+9 = 15\text{ kmph}$. 9. A boat running upstream takes 8 hours 48 minutes to cover a certain distance, while it takes 4 hours to cover the same distance running downstream. What is the ratio between the speed of the boat and speed of the water current respectively? A. 8 � If the speed of the stream is 5 km/hr, find the time taken by the boat to go 54 km downstream. A. 3 hours. B. 2 hours. A canoe traveled Downstream with the current and went a distance of 15 miles in three hours. On the return trip, the canoe traveled Upstream against the current. It took 5 hours to make the return trip. Find the rate of the current.� Renee rows a boat downstream for 27 miles. The return trip upstream took 24 hours longer. If the current flows at 4 mph, how fast does Renee row in still water?.

Before learning the concepts of the exam one must be aware of the terms that are used in the questions. When the boat moves against the current of the river i.

It is known as upstream speed. Remember it with UP as going up the hill means against the direction of the force speed of the river. When the boat moves with the current of the river i. It is known as downstream speed.

Remember it with DOWN as going down the hill means towards the direction of the force speed of the river. Type 1 : When the distance covered by boat in downstream is same as the distance covered by boat upstream.

The speed of boat in still water is x and speed of stream is y then ratio of time taken in going upstream and downstream is,. It takes him twice as long as to row up as to row down. Find the rate of the stream of the river. A man can row certain distance downstream in 2 hours and returns the same distance upstream in 6 hours. If the speed of stream is 1.

Find the distance between two places? A professional swimmer challenged himself to cross a small river and back. If it took him 15 mins more to cover the distance upstream than downstream, then find the width of the river? Find the average speed of a boat in a round trip between two places 18 km apart.
