Under normal circumstances, it takes about 30 minutes to travel to the extremities (fingers and toes) and return to the heart.
When the Blood pressure is low, the time taken increases, and when the pressure is high, the time taken reduces.

I agree with the 1 minute answer. The heart pumps 4-5 liters of blood per minute (more when exercising.) The total volume of blood in a human adult male is 5 liters.
On average, the entire blood volume is circulated each minute. A particular drop of blood may take more time if goes to your feet or less time if goes to your shoulder.

For a person at rest, it takes just about one minute. If you are more active, it will take less time. Exactly how long depends on several things: the rate at which your heart beats, how big your heart is, and, to a certain extent, how big you are as well.
A person's heart beats about 65 to 75 times a minutes. This is called the beat rate. With each beat, the heart pumps about 60 to 70 milliliters of blood. If you multiply the two values together, you find that the cardiovascular output is just about four to five liters per minute.
