SSC CGL Mocks � Just Rs. � Let speed of boat = $x$ km/hr and speed of stream = $y$ km/hr Thus, downstream speed = $(x+y)$ km/hr and upstream speed = $(x-y)$ km/hr Using, time = distance/speed => $(\frac{60}{x+y})+(\frac{20}{x-y})=4$ => $\frac{15}{x+y}+\frac{5}{. x-y}=1$ �����(i) Similarly, $(\frac{40}{x+y})+(\frac{40}{x-y})=6$ => $\frac{1}{x+y}+\frac{1}{x-y}=\frac{3}{20}$ ����(ii) Solving equations (i) and (ii), we get: $x=24$ and $y=16$ $\therefore$ Speed of stream = 16 km/hr.

To solve river boat problems, we need to understand two concepts: The speed of a boat relative to the water is equal to the speed of boat in still water. What is the time taken by the boat to travel a distance of 30 km downstream?

In upstream motion, the speed of the boat is equal to the difference of the speed of boat in still water and the speed of river water. Problem: A motorboat going downstream overcame a raft at a point A; one hour later it turned back and after some time passed the raft at a distance 6. Find the flow velocity. The velocity of the river water is? Solution: The boat crosses the river by the shortest path if it moves perpendicular to the river current. The velocity of the boat in still water is equal to the relative velocity of the boat w.

Question: You cannot cross a river to an exactly opposite point if your speed in still water is less than the speed of river water. True B. He should swim in a direction? The velocity of the man in still water is equal to the relative velocity of the man w.

Hence, the man takes the shortest time when he swims perpendicular to the river velocity i. Problem: A boat must get from point A to point B on the opposite bank of the river moving along a straight line AB that makes degree angle with the flow direction. If distance AB is 2. The velocity of the boat relative to the ground should be along the line AB.

Question: To cross a river in minimum time, your speed relative to the water should be perpendicular to the river flow. At what angle to the stream direction must the boat move to minimize drifting?

Solution: The drift is zero if boat reaches directly opposite point. The boat cannot cross the river to an exactly opposite point. Exercise: A boat must get from point A to point B on the opposite bank of the river. The distances BC and AC are equal. What is the minimum speed of the boat relative to the water? Exercise: A man can swim with a speed of 4. How long does he take to cross a river 1. How far down the river does he go when he reaches the other bank?

Two swimmers leave point A on one bank of the river to reach point B lying right across on the other bank. One of them crosses the river along the straight line AB while the other swims at right angles to the stream and then walks the distance that he has been carried away by the stream to get to point B. What was the velocity u of f his walking if both swimmers reached the destination simultaneously? There are two boats at the same point on the bank.

One of the boat starts its journey along the bank, it travels a distance 1 km upstream, and return back. Simultaneously, another boat starts its journey to the other bank by shortest path and returns back.

Which of the boat returns to the starting point first? From a point A on a bank of a channel with still waters a person Boat And Stream Pdf By Abhinay Sharma Youtube must get to a point B on the opposite bank. All the distances are shown in the figure. The person uses a boat to travel across the channel and then walks along the banks to point B.

We substantially have any questions, a poignant word is "little. Most years afterthis film is not for we, this sort of vessel can change in opposite sizes. How will a vessel be transported.
