Luden [163]

we know that

1) Lily swims a $100$ -meter race

2) She swims the first half in $27.8$ seconds

3) She swims the second half in $30.12$ seconds

To find the total time to swim the whole race sum the time in the first half plus the time in second half

$(27.8+30.12)=57.92\ seconds$

therefore

<u>the answer is</u>

$57.92\ seconds$
