Calculate the correct value:
 
Data for the motion of an object are given in the following table. State whether the speed of the object is uniform or non-uniform. Find the average speed.
 
Time (\(s\))
\(0\)
\(10\) \(20\) \(30\) \(40\) \(50\) \(60\) \(70\) \(80\)
Distance (\(m\) \(0\) 5 14 17 24 30 31 42 44
 
The speed of the object is
 
Average speed \(=\) \(m/s\)
 
[Note: Enter the answer upto 2 decimal places.]
