It can differ. If they team at bat keeps hitting the ball and doesn't get out, the inning would be longer. If the pitcher is striking out, the inning is shorter.
depends the time varies but an inning is finished when both teams get three outs
The 7th inning stretch (assuming your talking about baseball) is approximately 15 minutes.
It can go on for hours ...
An inning doesn't have a set length in time; an inning is simply the period within which the team at bat continues to get to bat until that team has three strikes. Theoretically, if a team never got a strike, an inning could go on indefinitely.
There's no specific time limit for each inning in softball. Each inning lasts as long as it takes for both teams to get 3 outs. In certain leagues there can be time limits on the whole game so teams might not be able to complete the full 7 innings of a game.
the batter will resume his at bat the next inning with a clean count, as long as he didn't make the last out (strike out fly-out, ect)
baseball doesn't have half time, just the 7th inning stretch
The most I can find is six, by the Oakland Athletics vs the Cleveland Indians during a 45-minute-long ninth inning on September 3, 1983.
You probably mean 'inning.' An inning continues until each team has recorded three outs against the other team. In other words, there is no time limit for an inning in American Baseball; both teams have to record three outs.
On average a nine inning baseball game normally runs 3 hours.
