The fewest number of days over which the tournament can take place is 5 days.
<h3>How to calculate the number of days?</h3>
As each team plays with other team Once and we have total 5 teams so number of matches will be (4+3+2+1)
Counted as team 1 plays with all other teams = 4 matches
Team 2 plays with team 3,4,5 =3 matches
Team 3 play with team 4,5=2 match
And the last match is between team 4 and team5
Total match = 10 and can be played two matches per day:

k^2 - 2k = 4
Simplify : k+2 = 4
<u> - 2 - 2</u>
k = 2
