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