Q. 105.0( 2 Votes )

Define average speed with example.

Answer :

The average speed of a body is the total distance travelled divided by the total time taken to cover this distance. The speed of a body is usually not constant and the distance travelled divided by time gives us the average speed during that time. For example, a car which travels a distance of 100km in 4hours, the average speed is = 25km per hour. Although the average speed of the car is 25km per hour, it does not mean that the car is moving at this speed all the time. When the road is straight, flat and free, the speed may be much more than 25km per hour but on bends (curved road), hills or in a crowded area, the speed may fall well below this average value. We should remember that:
Average speed=.
