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.
Can a body have nonzero average speed but have zero average velocity give example?
An object moving in a circular path at constant speed will have a non-zero average speed and zero average velocity since velocity is a vector parameter,
What is a non-example of average speed?
The colour green is a non example of average speed.
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.
How do you define average speed?
average speed is the average rate of movement, for example, the number of feet traveled on a yard.average speed is the-total distance/total time.

When is average speed of an object not equal to average velocity?
For example, an object goes in a circle, at a speed of 50 km/hour. The average speed is 50 km/hour; the average velocity is zero.
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. If a body goes round a circular path then distance covered by one full rotation will be 2 pi r But the total displacement is 0. Hence the average speed exists but average velocity does not exist.
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
