Question

An object travels 16m in 4s and then another 16m in 2s. What is the average speed of the object? ​

Answer 1

Answer:

the average speed will be 12.

Answer 2

Explanation:

Case : 1

when distance is 16 m and time is 4 s

speed (S1) = 16/4 = 4 m/s

Case : 2

when distance is 16 m and time is 2 s

speed (S2) = 16/2 = 8 m/s

Now, Average speed = S1 + S2/2

Average speed = 4 + 8/2

Average speed = 12/2

Average speed = 6 m/s
