an object travels 16 metre in 4 seconds and then another 16 metre in 2second what is the average speed of the object

6m/s

Explanation:

Given the information :

an object travels 16 metre in 4 seconds and then another 16 metre in 2second.

what is the average speed of the object?

First portion of travel:

Distance = 16 meters

Time = 4 seconds

Second portion:

Distance = 16 meters

Time = 2 seconds

Speed is calculated as the proportion of distance traveled to the time taken.

Speed = distance / time

First portion :

Speed attained

Distance / time = speed

16 meters / 4 seconds = 4m/s

Second portion:

Speed attained

Distance / time = speed

16 meters / 2 seconds = 8m/s

Average speed :

(first portion + second portion) / 2

(4m/s + 8m/s) / 2

12m/s ÷ 2

= 6m/s
