Question

Shyam goes to the market from his home which is 50m away from the shop in 20
sec. On his way back he visited his friends house which is 10m away from the shop in 10 sec.
Find the average speed and the average velocity.​

Answer 1

Answer:

speed = 2m/s , velocity = 1.33m/s

Explanation:

speed = (total dist. travelled) / (total time)

           = 50+10 / 20+10................it is not relative to the shop

             = 60/30

                = 2m/s

velocity  = (net dist. travelled) / (total time)

               = 50 - 10 / 20+10 ..............unlike speed it is relative to the shop

                = 40 / 30

                 = 4/3 = 1.33m/s
