In a particular game, there can be eight players at one time on the pitch and they last for seventy minutes. In the total duration, six players substitute with each player. All the players are then for the same time on the pitch including the substitutes. Can you calculate the time each player was on the pitch?
The total number of players = 8 + 6 = 14 According to the question, only eight players can be present on the field. Thus calculating the total time: 70 * 8 = 560. Since we know there are 14 players we divide by 14 to get 40.
