284 kilometers per hour is about nine-tenths as fast as an Arrow (archery).
In other words, it's 0.87980 times the speed of an Arrow (archery), and the speed of an Arrow (archery) is 1.1370 times that amount.
(250 g arrow fired from 60#/28" bow)
A 250 gram arrow will reach speeds of approximately 322.8 kph when fired from a 60-lb, 28-inch draw bow . Archeological evidence from the Ahrensburg valley near Hamburg, Germany indicates that arrows have been used since at least 11 to 12,000 years ago.
