Question

An object travels 32 m in 4 sec and again it travels 32 m in 2 sec . Then what is its avarage speed .​

Answer 1

Answer:

10.67 m/s

Explanation:

av.speed = total distance/total time taken

= 64/6

= 10.67 m/s

Answer 2

Answer :

An object travels 32m distance in 4s and another 32m in 2s.

We have to find average speed of object$.$

★ Average speed is defined as the ratio of total distance travelled to the total time taken.

• v = d / t

It is a scalar quantity having only magnitude.

It can't be negative or zero.

SI unit : m/s

⧪ Total distance travelled :

⭆ d = d₁ + d₂

⭆ d = 32 + 32

⭆ d = 64m

⧪ Total time taken :

⭆ t = t₁ + t₂

⭆ t = 4 + 2

⭆ t = 6s

⧪ Average speed of object :

➝ v = d/t

➝ v = 64/6

➝ v = 10.67 m/s
