Since we want to calculate for the same rate, we can use the same ratio of won games to total games.
The given ratio is:
[tex]r=\frac{20}{60}=\frac{1}{3}[/tex]For the whole 120-game season, the total is 120 and let's call the number of won games by n, so:
[tex]\begin{gathered} r=\frac{n}{120} \\ r=\frac{1}{3} \\ \frac{1}{3}=\frac{n}{120} \\ \frac{120}{3}=n \\ 40=n \\ n=40 \end{gathered}[/tex]So, at this rate, they will win 40 games.
