The distance traveled in a particular time on a sailboat is dependent on four primary factors, 1) the length of boat's waterline, 2) the strength of the wind, 3) the angle of the wind relative to the line of intended travel and 4) ocean currents. 1) The longer the waterline, the faster a displacement vessel can go. Planing boats are not limited by waterline as they actually rise above the water. A typical 32' to 42' long sailboat has a maximum hull speed of roughly 6 to 7 knots (nautical miles per hour). 2) If the wind is less than 10 knots, you won't be doing six knots. No wind, no speed. 3) Going across the wind is the fastest point of sail. Going directly into the wind (by means of tacking; like climbing a mountain using switchbacks) is the slowest as you will not be going directly to your intended goal. Typically, beating to windward will get you about 35 degrees to 45 degrees off from your direct line. 4) Currents can assist you (the Gulf Stream can hit six knots) or can slow you down. Check the charts in the area you want to transit. All that being said, you might expect to hit 100 miles or a bit more in a day, all things being average.
