This mostly depends on the person. Some people can take amphetamines their whole life and never get addicted, while others might find themselves addicted after only a few uses. In general, about 17% of people who try amphetamines end up addicted at some point.
Also, it seems that either you are susceptible to addiction or you aren't, and this predisposition is mostly hereditary. People who aren't susceptible probably won't become addicted even if they take the drugs for a long time. If you are susceptible you won't necessarily become addicted, but the more you take the drug, the greater the risk.
Amphetamines are relatively addictive compared to other drugs - i.e. a greater percentage of people are prone to addiction, and the addiction happens faster if it does happen. For comparison, 10-12% of people who get drunk at some point go on to become alcoholics, while as many as 75% of people who try tobacco end up smokers.
These numbers are from one study, and they seem accurate to me based on personal experience, but there is a lot of controversy around this issue in the scientific community and good, unbiased research is very hard to find.
Take no more then 4 nights!!
It depends on the speed at which you walk, and how long you can sustain that speed.
3 to 9 months but the effects of meth addiction can last years
Don't take speed.
You need to know the speed, to see how long it will take you to travel that distance. Once you know the speed, divide the distance by the speed, to get the time.You need to know the speed, to see how long it will take you to travel that distance.

Take the distance and divide by the speed of the train. That is how long it took for the train to travel.
It depends on how determined and serious they are about it. The amount of time varies for each person
1 hour
The speed of sound is only 768mph, so it'll take a pretty darn long time.
At what speed?
Depends on your travelling speed.
That depends on the speed. Divide the distance by the speed.
