Evan loves to compete in triathlons. At his most recent race, he finished in 189 minutes. That is 10% less time than his previous race took. What was Evan's finishing time at the previous race?

x = 210 minutes

Step-by-step explanation:

We can say that the previous race's finishing time was x and it was equal to 100% or 1.

We know that the current race's finishing time which is 189 minutes is 10% less than previous one's finishing time, so current race's finishing time can be said to be equal to 90% or 0.9.

Using the ratio and proportion, we can calculate the x to be,

1 : x

0.9 : 189

0.9 : 1  =  189 : x

0.9 * x = 1 * 189

x = 189 / 0.9

x = 210 minutes

answer: answer is c!

ok i got to organize the

3/15 and 12/55
