The speed of a stream is 3 mph. A boat travels 8 miles upstream in the same time it takes to travel 14 speed of the boat upstream and downstream path downstream.

What is the speed of the boat in still water? When you're traveling upstream, you are moving against the current, resisting the stream's flow, and so your rate is slowed by however fast the stream is moving which in speed of the boat upstream and downstream path case is 3mph; therefore, your upstream rate is represented by "r The reason you can ignore the x is because the "x" that represents time in both cases are equal and it would not affect your final values because they would equally affect each equation.

The time is equivalent for the two the situations. You see, if it's going against the 3mph current, it goes 8mph, but if it's going along WITH the 3mph current, it goes 14mph. Trending News.

A boatman takes 3 hours 45 minutes to travel 15 km downstream and takes 2 hours 30 minutes to travel 5 km upstream of a river. What is the speed of the stream of the river in km/h? Let b be the speed of boat and s the speed of stream in kmph. Downsream it took minutes to travel 15 km, or 75 minutes to travel 5 km. Downstream speed = b + c. When a boat travels against the current, it travels upstream. In this case, its total speed is. Upstream speed = b ? c. Problem. The speed of a boat in still water is 30 mph. It takes the same time for the boat to travel 5 miles upstream as it does to travel 10 miles downstream. Find the speed of the current. The boat�s speed going downstream is four miles per hour faster than its speed going upstream. Find the boat�s upstream and downstream speeds. upstream 8 mph, downstream 12 mph. In the distance, they meet on the path. Ethan�s speed is six miles per hour faster than Leo�s speed. Find the speed of .
