Question

estelle trained all month for the 100-meter dash at her schools annual track meet. her time at the track meet was her fastest time yet, 12.5 seconds. the time she predicted based on her training was 2% more than that. what time did estelle predict?
square seconds

Explanation:

Step1: Find 2% of 12.5

To find 2% of 12.5, we use the formula \( \text{Percentage of a number} = \text{Number} \times \frac{\text{Percentage}}{100} \). So, \( 12.5 \times \frac{2}{100} = 12.5 \times 0.02 = 0.25 \).

Step2: Add this to the original time

The predicted time is the original time plus the 2% increase. So, \( 12.5 + 0.25 = 12.75 \).

Answer:

12.75
