Q.6 Define average speed and uniform speed.

Ans.
Average Speed:- The average speed of a body is the total distance travelled divided by the total time taken to cover this distance.
Average Speed = Total distance travelled / Total time taken
eg. For a car which travels a distance of 100 km in 4 hours , the average speed is 100/4 =25 km/hr.

Uniform Speed:- A body has a uniform speed if it travels equal distances in equal intervals of time,
no matter how small these intervals may be.
Eg. A car is said to have a uniform speed of 20km/hr,if it travels 10 km every half hour.
