How do you solve (iii)?????

Answers: (i) 14:44               (ii) 18.2 km/h                      (iii) ???????

I tried.. ----->  The winner finished before Ben by 51.2 seconds
Ben took (33*60) 1980 seconds to run the 10 000 metres, while the winner took (1980-51.2) = 1928.8 seconds
MS: (iii) 32 mins 8.8 seconds

Sooooooooo the thing is how do you write 1928.8 seconds in mins and seconds? I understand it's 32 minutes, but how do we get the exact number of seconds taken??? 
TYYY
