Question

The Red Sox have won 3 World Series titles in the last 11 years. At this rate, how long will it take them to win 20 World Series?

Answer 1

The answer is 74 years. do 11/3=3.67. Then 3.67x20 =73.4 and since that .4 is not a full year you would have to round up to 74

Answer 2

73 1/3 years
What I did was use a proportion:

11/3 and x/20
Then you cross multiply:

3x=220
Then solve.
