It varies widely depending in part on strength. On researcher calculated that the median path length for U.S. tornadoes from 1950 to 1982 was just under 1 mile, which works out to a duration of just under 2 minutes (assuming an average speed of 30 mph).
However, the median if calculated today would probably be better documented as we have improved in our ability to find the weaker, shorter lived tornadoes.
Very destructive tornadoes. Median duration varies with intensity, ranging from 45 seconds for F0 tornadoes to 47 minutes for F5 tornadoes. Furthermore, these figures are only medians, and values can vary significantly either way. Brief touch downs have been observed to have lasted as little as 10 seconds while the longest duration on record was 3 hours and 29 minutes. For strong tornadoes durations of 10 to 20 minutes are not uncommon, with violent tornadoes being in the range of 20 minutes to an hour.
