Answer 2

Order of Finish in the Race

To determine the order in which Olga, Galina, Vera, and Zoya finished the race, we need to compare the times it took each of them to complete the race.

According to the information provided, Olga completed the race in 1/3 minute, Galina in 17/60 minutes, Vera in 3/10 minute, and Zoya in 4/15 minute.

To compare these fractions, we need to find a common denominator. The least common denominator for 3, 60, 10, and 15 is 60. Let's convert the fractions to have a denominator of 60:

- Olga's time: 1/3 minute = 20/60 minute - Galina's time: 17/60 minutes (already in terms of 60) - Vera's time: 3/10 minute = 18/60 minute - Zoya's time: 4/15 minute = 16/60 minute

Now that we have all the times in terms of 60 minutes, we can compare them to determine the order of finish.

Comparing the times, we can see that: - Olga finished first with a time of 20/60 minute. - Zoya finished second with a time of 16/60 minute. - Vera finished third with a time of 18/60 minute. - Galina finished last with a time of 17/60 minute.

Therefore, the order in which they finished the race, from first to last, is: Olga, Zoya, Vera, Galina.
