Let a body travels with a speed of 63km/h for 1h. After that let it travels with a speed of 1km/h for another hour. The total distance travelled(D) will be
(63*1 + 1*1)=64km. Also total time taken(T) will be (1+1)=2h. Thus,
Average speed=D/T=64km/2h=32km/h ;which is clearly higher than the final speed(1km/h).
Thus, Av. speed may be higher than the final speed.

Why do you use average speed?
The concept of average speed is somewhat simpler than "instantaneous speed".
Is it easier to calculate speed or average speed?
I'm sure that average speed would be easier to calculate than instantaneous speed. To calculate average speed, just take the time that it takes to travel between two points, and divide that into the distance between the points.
Jake and Brenda drove at a speed of 30 mph for 1 hour. Then they turned around and drove 45 mph until they were back where they started. What is true about their average speed and average velocity?
Their average speed is the harmonic mean of 30 and 45 while their average velocity is zero.
What is the average speed when driving 360 miles In a semi truck?
The average speed depends on a lot more things than the vehicle: Average speed = total distance/time. If you consider average speed over a week, you will be including the time when you are sleeping, or eating or filling up and not moving at all. Road and traffic conditions, weather, your driving style, speed limits (and whether you obey them) will all affect average speed.
Is a 113 IQ average for 5-year-old female?
No, it is much, much higher than average!
What does the experiment suggest about the average speed of hydrogen molecules compared with the average speed of molecules in the air?
The experiment suggests that the average speed of hydrogen molecules is higher than the average speed of molecules in the air. This is because hydrogen molecules are lighter and have a higher root mean square speed due to their lower mass.
If a car is speeding up its initial speed is what than its final speed?
If a car is speeding up, its initial speed is less than its final speed. As the car accelerates, its speed increases over time, so the initial speed is lower than the final speed attained during acceleration.
If a car is speeding up its initial speed is than its final speed?
If a car is speeding up, it's initial speed is LOWER than it's final speed.

FSB speed of intel core2?
The average FSB speed for an Intel Core 2 processor is about 1333 M. However, this speed depends greatly on the model, some are much higher or lower than that!
If the final velocity will be less than initial velocity the object is increasing speed or decreasing speed?
If the final velocity is less than the initial velocity, the object is decreasing speed. The object has slowed down or its speed has decreased compared to when it started.
What is the maxim speed of a human?
Usain Bolt holds the world record for the 100m sprint. He did this in 9.69 seconds, which gives an average speed of 23.08mph (10.32m/s). As this is an average speed the maximum speed will be a bit higher than this. so to answer your question the maximum speed of a human is about 25mph
Jake and Brenda drove at a speed of 30 mph for 1 hour Then they turned around and drove 45 mph until they were back where they started What is true about their average speed and average velocity?
their average speed is greater than their average velocity.
Can a mean average ever be higher than a median average?
Yes. If the predominant data are higher than the median, the mean average will be higher than the median average. For example, the median average of the numbers one through ten is five. The mean average is five and one-half.
When is the speed of sound near the ground less than the speed of sound higher up?
If the speed of sound near the ground is less than the speed of sound higher then in this special case the temperature at the ground must be less than the temperature higher up. Usually the temperature at the ground is warmer than the temperature high up in the sky. The speed of sound changes mainly with the temperature.
Can instantaneous speed ever be greater than its average speed?
yes
Can the median ever be higher than the average?
Yes. It can be higher or lower
