A game of football with 11 players lasts for exactly 90 minutes. There are four substitutes that alternate equally. If each player plays for the same length of time, what is the duration? (A) 22.5 mins (B) 18 mins (C) 66 mins (D) none of these

(A) 22.5 mins

Step-by-step explanation:

Given data:

Duration of the match = 90mins.

Number of substitutes = 4.

Solution:

Since Each of the four (4) substitute players alternated equally, simply means each of the 4 players spent an equal amount of time on the football pitch.

= 90mins/4

= 22.5mins.

Each player spent 22.5minutes on the football pitch.
