To determine average speed, you need to know what distance the object traveled in meters over how long it took the object to travel that distance in seconds.

Does the speedometer of a car read average speed or instaneous speed?

In a car, the speedometer measured Instantaneous speed. This comes from the assumption that the car does not slow down and speed up fast enough for the speedometer to be able to give an average of the changing speed.

What is the relation between instantaneous speed and instantaneous velocity?

If I drive away from my house at 8:00 in the morning and return at 6:00 PM that same evening with 50 more miles showing on the car, you know immediately that my average speed for the day was 5 mph. But you don't know a thing about how much of that time I was stopped, how much in motion, or what my speed was at any moment between 8 and 6, because there's no necessary relationship between instantaneous and average speed. I guess it's probably true to say that there has to be some instant during any period of time when the instantaneous speed must be equal to the average speed during the same period. That sounds like a nice theorem, and its proof ought to be good for some mathematical recreation, but it doesn't seem too useful.


How do you know a object's speed and velocity?

Velocity = Delta-x / Delta-t, where x is position, t is time, and "Delta" is the "Change in" operator.Velocity is a vector, so I probably should have written x as x, or x-arrow, or some other notation to indicate it was a vector quantity, but putting an arrow hat on something is a little difficult to do here, and just making it bold is kind of subtle and could be missed.Speed is the magnitude of the velocity vector.


Can you calculate your average speed while walking at different speeds?

For the speed of a single pedestrian, measure the time it takes him/her to walk a set distance (for example 10 meters) and divide the distance by the time. For the average speed of a pedestrian find a large number of people and measure the speed of each person and find the average by summing all the speeds and dividing by the number of people who took the test.

What two things must you know to determine avaerage speed?

To determine average speed, you need to know the total distance traveled and the total time taken to travel that distance. Divide the total distance by the total time to calculate the average speed.


What are two things must you know to determine average speed?

To determine average speed, you need to know the total distance traveled and the total time taken to travel that distance. The average speed is calculated by dividing the total distance by the total time.


In order to determine speed you must know two things?

To determine speed, you need to know the distance an object travels and the time it takes to cover that distance. Speed is calculated by dividing distance by time.


What three things must you know to determine velocity?

To determine velocity, you must know the object's distance traveled, the direction in which it traveled, and the time it took to travel that distance. Velocity is a vector quantity that includes both speed (magnitude) and direction.


What must you know to determine speed?

To determine speed, you must know the distance traveled and the time taken to cover that distance. Speed is calculated as distance divided by time. You may also need to know the direction of motion if you want to determine the velocity, which includes both speed and direction.


What can you determine if you know the distance in a given time?

What is the acceleration in science if you know average speed and time?

If you know average speed then you cannot determine the acceleration: the very nature of being a average hides all the increases and decreases in speed which are the accelerations (technically, acceleration is change of speed in a direction). All average speed tells you is the constant speed at which you require to travel to cover the given distance in the given time; as the speed is constant, the acceleration is zero.


How do you convert gallons per hour to gallons per miles?

You first need to know what your average speed is to determine how many miles have been traveled


What two things must you know to determine speed?

Speed is the rate at which an object moves. To determine the rate at which that object moves, we'll have to look at a given distance that it covered when it moved, and at the time it took to cover that distance. The distance per unit of time is the speed of the object.
