Question

diana ran 300 yards in 72 seconds. then she ran 300 yards in 52.2 seconds. how much faster was dianas second time? you may use the calculator tool in the menu.

Explanation:

Step1: Determine the formula

To find out how much faster the second time is, we use the formula: \( \text{Difference}=\text{First time}-\text{Second time} \)

Step2: Substitute the values

Here, the first - time \( t_1 = 72 \) seconds and the second - time \( t_2=52.2 \) seconds.
\( \text{Difference}=72 - 52.2 \)

Step3: Calculate the result

\( 72-52.2=(72.0 - 52.2)=19.8 \)

Answer:

\( 19.8 \)
