5 feet per second. 3 mph. A walking pace.
Blood is mostly water. A good rule of thumb in water piping systems is 5 fps. Faster and you're using too much energy to pump. Slower and you bought too much pipe. Turns out (of course) the human body is pretty well optimized.

There is a snake that we call 3 steps. It receives this name pecause after it bites you you take 3 steps and then fall dead. Keep in mind that in this brief span of time you are bitten in the ankle and the poison has to travel all the way to your brain in order for the neurotoxin to take effect. All this has to happen in like 2 seconds. I used to think it was not very fast, but a doctor told me it is faster than most people think. Take a small rubber ball the size of your fist. Make a hole in it, fill it with water and then press it as hard as you can. Now do the same thing but with a tube connected to the hole. The effect is much more violent. Were you to connect the tube back to the ball and have a set of valves to prevent the water from flowing back, then you would have something similar to the human heart. Not only this, but remember that blood is under pressure, it is not a lot, but the reason we don´t explode is that the atmosphere holds some 31 kilograms per square inch of pressure this contributes to the efficient action of the bloodstream. I know I did not answer your question. But your answer would depend on size, tmaller is faster. Age, the younger the faster. Exitement, Sex, physical constitution,etcetera. In average I would say off the top of my head... some 5m/s make the conversion to miles per hour

Not too fast, relative to a car's speed, but probably faster than you'd think. I'd estimate blood to travel about the same speed as you walk, but it all depends on your heart rate, blood pressure, and... well... quality of blood.
I'd like to add that I read a few messages down where it says 3 ft per second. Yeah, that's about how fast you walk (if going relatively slow).

What are u all nuts, it has to travel fast becuase if it went slow then u guys would be dead. When blood leaves your heart, it travels about three feet per second. That's the length of one yardstick! As the blood gets closer to the smaller arteries, it slows down. A drop of blood travels from your heart down to your toes and back again in about one minute. Got this info on this site, http://calbears.findarticles.com/p/articles/mi_hb3569/is_199610/ai_n8391071.

60 mph, Because if your blood was slower it couldn't get to the heart fast enough, there for you would die.

This maybe a bit over your head but is the most detailed explanation I have seen so far.

Miles per hour! Thats a very crazy question.

Not fast at all. But good question.
