Time taken to shoot 10 images is 1 secTime taken to shoot 6 images is 0.6 sec.Assuming that the full revolution of ball is not considered thenSpeed = distance/time= 15/0.6= 25m/sIf we consider that in five shots the ball has exactly done two revolution then we have to also consider that it has travelled only 12.5 MTS.Then the speed is 12.5/0.5=25 m/s

Given .. (1) time taken to take 10 shots=1 sec ==> time taken to take one shot= 1/10 sec (2) Distance travelled by ball while camera took 6 shots =15 meter We know , speed= distance/time Distance=15m Time= Not known... lets find out the time to take six shots Fist shot was taken after = 0sec (as first short was taken at beginning) Second shot taken after = 1*(1/10) = 1/10 seconds Third short taken after = 2*(1/10) =2/10 seconds Similarly .. sixth shot taken after = 5*(1/10) =5/10 Now.. speed = distance/time = 15 / (5/10) = 30 m/second Hope, it helps.
