Question

An ice hockey game is made up of three 20-minute periods with a 15-minute intermission after each of the first and second periods. A game started at 5:21 p.m. The clock was not stopped during the game. At what time did the game end?

Answer 1

Hi Le,

Given the information provided above, and since the clock did not stop during the hockey game, the game lasted a total of 90 minutes (1 hour-and-30 minutes, or 1-and-one-half hours).

Therefore, the hockey game ended at exactly 6:51 p.m.
