meters
kilometer
The highest race speed recorded over two furlongs is 70.76 km/h (43.97 mph) and was achieved by Winning Brew trained by Francis Vitale (United States), at the Penn National Race Course, Grantville, Pennsylvania, United States, on 14 May 2008.

70.76/60 = 1.18 km/hr

1.18/60 = .01km/minute

.01/60 = .0003km/second = .3m/second

I stick by my answer.
