to find out the velocity we apply the formula v=d/t mean velocity=displacement divided by/ time taken 

okay now ill do an numerical for you

q1)A cyclist completes half round of a circular track of radius 318 m in 1.5 minutes.Find its speed  and velocity?

solution:

radius of track r=318 m
time taken t  =1 min 30s =90s (1 min =60s +the remaining 30s)
distance covered= pi x radius
                         =3.14x318m = 999m

displacement =2r                
                    =2x318m           =636m
speed=distance/time
          =999m/90s                  =11.1ms-1


velocity=displacement/time taken
           =636m/90s     =7.07 ms-1

speed=11.1ms-1
velocity= 7.07ms-1
