Answer 1

Given

At a race last month, Francesca finished in 190 minutes.

At her next race, she finished with a time that was 10% longer.

To find: What was her finishing time at the most recent race?​

Explanation:

Let x be the finishing time of the most recent race.

Since the finishing time of the first race is 190 minutes, and the finishing time of the second race is 10% longer than 190 minutes.

That implies,

$\begin{gathered} Finishing\text{ time of the second race}=190+10\% \\ =190+\frac{10}{100} \\ =190+0.1 \\ =190.1\text{ }minutes. \end{gathered}$

Hence, the finishing time of the most recent game is 19.01 seconds.
