You can calculate it from the formula for velocity
v=\(\frac{s}{t}\)
if it travels 450 yards in 15 seconds
s=450 yards t= 15s
1 yard = 3 feet so
s= 1350 feet
v=\(\frac{1350}{15}=90 \frac{feet}{s}\)
so if in one second it travels 90 feet, in \(\frac{1}{3}\) of a second it travels \(\frac{90}{3} =30\) feet
