Answer:

playing time: The basketball game consists of four quarters of 10 minutes each. Teams play one-way for two quarters, the other way for the next two. There is a two-minute interval between the first and second period, and also between the third and fourth period, with 15 minutes for halftime.

Time out: NBA rules state that each team is given six timeouts each during the course of a 48-minute game, with one 20-second timeout allowed per half and each overtime period. Each team is also limited to no more than three timeouts in the fourth quarter.

substitution: There is no limit to the number of substitutions a team can make during a game. When a player is fouled out or leaves the court for any reason, they must be replaced by a substitute.
