There are 60 minutes in an hour, and 60 seconds in a minute, and so 1 hour is:. The average velocity is This means that the average velocity can also be stated as At that time, the cage was If the average velocity of the pigeon is The pigeon's home is at position x 2 , which is:.

Velocity describes the rate at which an object changes position. For scientific problems, you should use meters or another metric unit of distance, but for everyday life you can use whichever unit you're comfortable with. Find the total displacement. The displacement is the object's change in position, or the distance and direction between its starting point and end point.

For our first example, we'll use an object moving at a constant speed in one direction: Let's say a rocket traveled north for 5 minutes at a constant rate of meters per minute. Find the total amount of time spent. In our example problem, the rocket moved forward for 5 minutes. You can express average velocity in any units of time, but seconds are the international scientific standard. Calculate average velocity as displacement over time. If you know how far the object traveled, and how long it took to get there, you know how fast it was going.

Remember to include the direction such as "forward" or "north". Solve more complex problems. If an object turns or changes speed, don't get confused. Average velocity is still calculated only from the total displacement, and the total time. It doesn't matter what happens in between the start point. Charlotte Maths Solutions For Any Questions walks north 1 meter, then walks west 8 meters, then south 1 meter.

It takes her 4 seconds total to walk this distance. Draw a diagram on a piece of paper, and you'll see that she ends up 8 meters west of her starting point, so this is her displacement. Determine that the best equation to use for this problem is the velocity equation.

Your first instinct may be to add both of the velocities and divide that number by 2 to Average Speed Of Pontoon Boat Workshop get your average. However, since we aren't given the times of each segment, we can't just assume that they take the same amount of time. If each segment took an hour, for instance, you can add the velocities and divide by 2. Not in this case, however. Take your velocity equation and solve for time. Plug in your values to find the times for each of the segments. To find the average velocity, we must find the total distance traveled and divide it by the change in time which is the times totaled together.

Then you solve. In this case, the average velocity happens to be the same as the average speed. This isn't always the case, however. Remember that the speed is not a vector quantity, so the direction is irrelevant. Calculate the average speed for the round trip. Mine's pretty pathetic. But draw your picture so you can visualize what's going on. Each segment, in this case, represents some unknown distance you'll call x. List all your given information�it doesn't have to look like mine or be set-up like mine.

We discussed earlier that your distance is some unknown value x. You also don't know your time, but it can easily be determined. Use your average speed equation and solve for the time. You will solve for the time for each segment. You will not have some specific number. You will have x in your answer, but that's okay! Add the times of the two segments you just obtained. That is your change in time or the time it takes for the automobile to travel.

You have two unknown distances that you have assumed are the same length. Simply add your two unknown distances together to find the sum. You now have the change in time and the total distance. Plug this into your average speed equation and you will obtain the answer.
