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?
