Question

a car moves from A to B with speed 20 metre per second then it returns with speed 40 metre per second find average speed also find average velocity ​

Answer 1

Answer:

average speed=(v+u)/2

=(20+40)/2

=60/2=30m/s

Answer 2

Answer:

a car moves from a to b

Explanation:

average speed =s1 +s1 /2

where s1 = 20m

s2=40 m

therefore 60/2 = 30m

here direction of car is same so average velocity = average speed

= 30
