There are 11 options for the first-place finisher. Once the first-place finisher has been determined, there are 10 remaining options for the second-place finisher. Therefore, there are 11 x 10 = 110 ways that first and second place can come without any ties.

There are 110 ways in which first and second place can come in a race with eleven people and no ties.

The first place can be taken by any of the 11 people, and the second place can be taken by any of the remaining 10 people. Therefore, the number of ways of selecting the first and second place is 11 x 10 = 110.
