an object moves 10m in the first 2 seconds, 20m more in the same direction in the next 8 seconds. Find the average velocity for the first 2 seconds then for next 8 seconds and also for the total journey.

average velocity = displacement/time
 
average velocity in first 2 seconds = 10/2 = 5 m/s
average velocity in next 8 seconds = 20/8 = 2.5 m/s
 
average velocity for whole journey = 30/10 = 3 m/s
