```							Dear studentDistance traveled per second = { 9,8,7,6,5,43,2,1,0,1,2,3,4,5,6,7,8,9,10}Sum = 55+45= 100 mAvg speed = 100/20 = 5 m/sRegards

```							i dont think you get that much time to solve as done by Saurabh Koranglesee the velocity time graph of above equation is a straight line so you should go by graph method graph is straight line (in particular :- two straight lines ) that is v=10-t for t10finding area of two triangles (base 0 to 10 and base 10 to 20) area = 50+50=100m=total distance=total displacement as velocity is always positive in this caseaverage spped = total distance/total time = 5m/s it may appear longer but its faster aprove if it helps you as it motivates me to answer more   :)
