When we move upstream, our speed gets deducted from the speed of the stream. Similarly when we move downstream our speed gets the speed of the boat in still water and. Example 1: A boat travels equal distance upstream and downstream. What is the speed of the boat in still water? Example 2: Speer boat travels equal distance upstream and downstream.

What is the speed of the current? Example 3: A boat is rowed down a river 28 km watwr 4 hours and up a river 12 km in 6 hours. Find the speed of the boat and the river.

Solution: Downstream speed is. Speed of current Downstream�Upstream speed. When the river is running at 1. How stiol is the place? A man rows a certain distance downstream in X hours and returns the same distance in Y hours. Example 5: Vikas can row a certain distance downstream in 6 hours and return the same distance in 9 hours. Example 6: Two ferries start at the same time from opposite sides of a river, travelling across the water on routes at right angles to the shores.

Each boat travels at a constant speed though their speeds are different. They pass each other at a point m from the nearer shore. Both boats remain at their sides for 10 minutes before starting. On the return trip noat meet at m from the other shore. Find the speed of the boat in still water and width of the river. Using iwe. Using ii. Stream: It implies that the water in the river is moving or flowing. Upstream: Going against the flow of the river.

Downstream: Going with the flow of the river. Still water: Speed Of The Boat In Still Water Is 15 Kilometre Per Hour Jacket It implies that the speed of water is zero generally, in a lake. Quicker Method to Speed Of The Boat In Still Water Game solve the Questions. Let the required distance be x km. Solution: Let the the speed of the boat in still water and of the river be x. Let a, b be the speeds of the ferries. Home Wafer. Maths Reasoning Boaf English. Share this page!

The speed of the boat in still water is 10 miles per hour. To find the speed of the current, we can substitute 10 for the B in any of our equations. We'll choose the easiest equation to work with: 12 = B+C. Speed of the boat or swimmer in still water = 1/2 * (Downstream Speed + Upstream Speed) = 1/2 * (18+12) = 15 km/hr Speed of the current = 1/2 * (Downstream Speed - Upstream Speed) = 1/2 * () = 3 km/hr Q 3 - A man swims downstream 28 km in 4 hrs and upstream 12 km in 3 hrs. Find his speed in still water and also the speed of the current. What is the speed of the boat in still water? SOLUTION: The current in a stream moves at a speed of 3km/h. A boat travels 40km upstream and 40km downstream in a total time of 14 hours. What is the speed of the boat in still water?
