Boat Upstream & Downstream - Tips, Tricks, Formula & Sample Questions

Let v be the speed of the boat in still water, and c be the speed of the current. First, recall that speed or velocity is a measure of the time required for an object to travel a certain distance.

The speed of an object is given by the following formula:. Letting v represent the speed of the boat in speed of the boat in upstream 8th water and c represent the speed of the current, we are given the following:. With this, we arrive at the following equations for the upstream and downstream speeds of the boat:.

To solve for the speed of the current cfirst solve each equation for the speed of the boat in still water v in terms of c. Then we can set these to expressions equal to one another and solve for c. That speed of the boat in upstream 8th. Notice upstrea if we add the two equations speed of the boat in upstream 8th part a to one another, c the speed of the current will cancel out and leave us with one variable to solve for, that being the speed of the boat in still water v :.

Thus, the speed of the boat in still water i. Let's take each part of this multipart problem one step at a time and all will be clear. Our formula tells us that the distance D is the product of the rate or speeed R and the time T.

We can solve our two equations for c by the elimination technique combining the two equations and eliminating the variable v :. Equation 2: 6. Equation 5: Equation 6: We can use either equation from part a to calculate speed of speeed in still water by plugging in our answer of 1.

Dividing both sides of equation by 6. Get a free answer to a quick problem. Most questions answered within 4 hours. Choose an expert upstrean meet online. No packages or subscriptions, pay only for the time you need. Add comment.

Hi Sabrina, Let's take each part of this multipart problem updtream step at a time and all will be clear. Using our given info, we can use our distance formula to set up our 2 equations: 1.

Q 5 - A boat covers a certain distance downstream in 6 hours and takes 8 hours to return upstream to the starting point. A motor boat travels 28 km upstream and then returns downstream to the starting point. Q 7 - A boat travels 32 km upstream and 60 km downstream in 9 hr.

Also it travels 40 km upstream and 84 km downstream in 12 hrs. Find the speed of the boat in still water and rate of the current.

It takes 6 hrs to swim to a certain distance and return to the starting point. Find the distance between the two points. Q 9 - A boat running downstream covers a distance of 30 kms in 2 hrs.

While coming back the boat takes 6 hrs to cover the same distance. If the speed of the current is half that of the boat, what is the speed of the boat?
