Top speed was 33 knots. Multiply by 1.15 to get miles per hour. Multiply by 5280 to get feet per hour. Now that you have velocity, using the equation d=vt, you can insert 887 (length of Iowa in feet) for d, put 200376 for v, and solve for t. 887/200376= .00443 ish, which is the time it takes in hours for the stern to reach the spot where the bow was at 33 knots. Now to conver to seconds, that'll be .00443*60*60, which is 15.9 seconds. So, if I converted correctly, the time it takes for an object moving at 33 knots to travel 887 feet is 15.9 seconds.
