Question

A dog runs 100 m in 20 seconds. He then comes back half the distance in 10
seconds and stops. What is the dog's average velocity?​

Answer 1

5m/s

Explanation:

Velocity=displacement/time

Average velocity=Total displacement /time

Displacement=50m

Time=10seconds

Velocity=50/10

=5m/s

Answer 2

Answer:

5m/s

Explanation:

velocity=s/t

average velocity=total displacement/ time

displacement=50

time =10

velocity=50/10

velocity=5m/s
