while travelling downstream, the speeds get added as the stream and boat are travelling in the same direction. So, in downstream journey, the speed equation becomes, x/(t d) = 9+3.� From home to work with a distance of 80km, it will take Marco 2 hours to travel if his average speed is 40km/hr.� A boat travels 3 hours downstream and covers 5 km more than the distance covered in 4 hours upstream. What is the speed of the boat in still water? Let S denotes the speed (in km/hr) of the boat in still water. UPSTREAM: This refers to anything having to do with the exploration and production of oil and natural gas. Geologic surveys and any information gathering used to locate specific areas where minerals are likely to be found is commonly called �exploration.� The term �upstream� also includes the steps involved Boat Upstream And Downstream Use in the actual drilling and bringing oil and natural gas resources to the surface, referred to as �production�. MIDSTREAM� The final sector of the oil and natural gas industry is known as �downstream.� This includes everything involved in turning crude oil and natural gas into thousands of finished products we depend on every day. Some of the more obvious products are fuels like gasoline, diesel, kerosene, jet fuels, heating oils and asphalt for building roads. Then the velocities of boat and stream are (in Kmph). A. 20,� Problems on Upstream and Downstream Motion. 7 min. Classes.

When we move upstream, our speed gets deducted from the speed of the stream. Similarly when we move downstream our speed gets added. Example 1: A boat travels equal distance upstream and downstream. What is the speed of the boat in still water? Example 2: A 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 in 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 far 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 back. On the return trip they meet at m from the other shore. Find the width of the river. Using i , we get.

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: It implies that the speed of water is zero generally, in a lake. Quicker Method to solve the Questions. Let the required distance be x km. Solution: Let the width of the river be x. Let a, b be the speeds of the ferries. Home G.
