Answer:
13 more consecutive wins required.
Explanation:
We know that the team has won 20 times, and lost 45 times, we can assume that they have not ever drawn a game.
Therefore we also know that the team has played 65 matches in total (20 wins + 45 losses = 65 total games).
To know how many games in total they must win to have a win rate of over 50%, we can divide the total number of games by 2 to get half of this value.
--> 65/2 = 32.5 games
now, it's impossible to win half of a game, so we simply round up to the next value to get 33.
To calculate how many more games they must win, simply subtract their current number of wins away from this value.
--> 33 games - 20 wins = 13 more consecutive wins required.
