Total distance covered by the body = 100m 
Total time taken by the body = 20s
Now , 
        average speed = total distance / total time taken 
                              = 100m/20s 
                              = 5m/s.

As the formula for average speed is average = total distance/total time taken by the body .
so the answer is 100 / 20 = 5
