Question

15% of Alina’s workout consisted of cardio exercise.

25% of Dane’s workout consisted of cardio exercise.

Which statement must be true?

Answer 1

If Alina’s workout was 80 minutes, and Dane’s workout was 48 minutes, they spent the same amount of time on cardio exercise.

Explanation:

Since the time difference depends on the initial amount of time, answer #1 is not right

Next, #3 is also not right since the difference is way to great.

Next, #4, we cannot tell how long the workouts of both were, so this is not right either
