In mathematics, a proof is a sequence of statements given to explain how a conclusion is derived from premises known or assumed to be true. The proof attempts to demonstrate that the conclusion is a logical consequence of the premises, and is one of the most important goals of mathematics. In mathematics, algebra is one of the broad parts of speed of the boat in still water problem, together with number theory, geometry and analysis.
In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols; it is a unifying thread of almost all of mathematics. Tsill want to derive a formula for the time it will take for the or to make a round trip, profiting off distance D if seed makes the trip upstream and then back downstream as well as directly directly across the river and.
So firstly, pdoblem, part A. Let's look at the upstream trip. Now upstream, the board will cover a distance of the over to on a net speed thhe the minus you. So the time it speed of the boat in still water problem take t one Speed Of The Boat In Still Water Is 8 Kilometers Per Hour Ep to travel upstream the total distance over to D over to divided by the speed. The im issue with the speed of the boat and you speed off the current. So obviously the boat is traveling against the current.
Hence the minus you, so we could write this as d over to inter V minus you now for the downstream part off the trip. As the boat comes back, the border cover again in distance off the over to back to its starting point. Speed of the boat in still water problem now the next it will be the plus you as travels with the current. So t two is now d over speed of the boat in still water problem the total distance, divided by the speed the bless you.
And so we can write this as d divided by tsill into the bless you. And so therefore, the total time for this trip will call it T is obviously wafer one yes, t two which is de over two into the minus. You bless de over to into the plus you.
And if we simplify this, this becomes the times Watr over v squared minus you square and this is your first answer. So the total time it will take for the boat to make a trip upstream and then back downstream is Devi over V squared minus you square. Now, for the next part of the question for the boat to go directly across the river, it must be angled against the current in such a way that the net velocity is straight across the river as we will show in the following diagram.
So from this diagram, the following equation weaken, see must be satisfied. The velocity off the boat relative. To show VBS must equal to the velocity off the boat relative to the water plus the speed of the current, which is the stilll off ih water relative to the shore, syill ws and using the notation that we've shown in the diagram This is simply the plus you and so the speed of the boat relative to the shore BBs We simply equal to the square root off the squared minus you squared and the time it takes to go a distance The over to across the river is t one recover the distance off deal with too divided by the velocity which is the square root off the squared minus you squared which weaken right as D Invited by two times the square root of V squared minus you squared.
Now the same relationship would be in effect for across for crossing back to the starting point. So t two then is the same as T one. So that journey beck is the same as the same time as the journey. And so you can speedd again the total time, the total time t simply t problfm plus t two, which is just two times t thhe and this is D speed of the boat in still water problem the square, root off the squared minus you squared.
So that would be the total time across that of Ah, back Now, Finally, we want to know why you has to be less than V. Well, if ln is speeed than you or these less than you, rather than the boat will not move upstream at all. So the speed of the boat will be less than the Speed Of The Boat In Still Water Is 15 Km Wr current, and the boat would not be able to move upstream.
