Question

The concept of average speed arises when speed is

Answer 1

Answer:

Explanation:

the concept of average speed arises how quick or slow body moves. We relate the time taken to cover distance.

for body A:                                               for body B:

speed = s1                                                speed =s2

time =t1                                                     time=t2

average speed= s1+s2/t1+t2

Answer 2

The concept of average speed is the ration of sum total of total distance travelled by the body and the time taken to travel that distance

Explanation:

• average speed is usually calculated by calculating the total distance travelled by a body in varying speed.

• The  speed is actually the distance travelled by the body to the time taken by the body. it is a scalar quantity because both speed and time are scalar quantity. On the other hand average velocity is an example of vector quantity because velocity is a vector quantity and displacement is also a vector quantity.
