Question 263507
You've got it.
.
But it might be best to think of it terms of the distance equation.
.
d = rt, where d=distance, r=rate, t=time
.
d = 1100 ft/sec * 3 sec
.
d = 3300 ft
.
Note the 'seconds' cancel, so the answer is in 'feet.'

Units of measure are important.  And if you keep track of the units, you sometimes can figure out how to solve the equation to get an answer in the correct units.
.
Good luck.
