If I walk 4 kilometers in an hour, my average speed during that hour was 4 km/hour. My instantaneous speed may well have been faster at times, and slower at other times, 4 km/hour is only the average.

What does average speed and average time have in common?
Apart from the fact that they are average, nothing. For example, the average time I spend sleeping has nothing to do with any average speed.
Why does speed distance divided by time give you only the average speed?
Because it does. :)
What is the average speed of the car traveling 300km in 6hrs?
Velocity (or speed) = Distance ÷ Time In this example, speed = 300/6 = 50 kph
A bus travel 120 km in 2 hourswhat is its average speed?
Velocity (or speed) = Distance ÷ Time In this example, speed = 120/2 = 60 kph
When are speed and average speed the same?
Average speed is an average value of speed over a given time. If your speed is constant (not changing), then your average speed will equal your speed at any given moment in time.
In what condition average velocity is equal to average speed give an example?
When an object is moving along a straight line at a variable speed, we can express the magnitude of the rate of motion in terms of average velocity.It is the same way as we calculate average speed.
Can a body have nonzero average speed but have zero average velocity give example?
Yes, a body can have a nonzero average speed but zero average velocity if it moves around a closed path and returns to its starting point. For example, if a car travels around a circular track at a constant speed, its average speed will be nonzero (as distance is covered), but its average velocity over the entire trip will be zero as the displacement is zero.
What is a non-example of average speed?
Average speed is not measuring the distance traveled in total, as that is total distance. For example, if a car travels 30 miles in 1 hour and 90 miles in the next 2 hours, the average speed is not calculated as (30 + 90) / 3 hours.

What is the average scram jet speed?
5 to 6 Mach... to give an example, the top speed of the 747 is only 0.9 Mach, the Concorde was 2.2 and the Boeing FA/18 Hornet is 1.8
Can average speed of a moving object be zerogive an example?
No, it can't. Average VELOCITY can be zero, though.
Is it possible for a body to have average speed but zero average velocity give reason and example?
Yes, it is possible. This can happen when an object changes direction but ends up at its starting point. For example, if a person walks a certain distance in one direction and then walks back the same distance, their average speed over the entire trip could be constant, but their average velocity would be zero since displacement is zero (ending at the same point).
What is an example where instantaniouse speed is differant from average speed?
This will happen any time the speed changes over time.
Can you say that the average speed is always less than the instantaneous speed example?
donkeys is the clue
Can average speed and speed per hour be equal?
Yes. For example, if you drive exactly 65 MPH consisently for an hour, your average speed will also be 65 MPH.
Can the average speed of a body be zero and can the average velocity of a moving body be zero?
Since speed is a scalar quantity, the only way the average speed can be zero is if the instantaneous speed is at all times zero, making it not a moving body, so no on the average speed. The average velocity, on the other hand, can easily be zero. The simplest example is you running in a circle.
