Respuesta :
we know that
1) Lily swims a [tex]100[/tex]-meter race
2) She swims the first half in [tex]27.8[/tex] seconds
3) She swims the second half in [tex]30.12[/tex] seconds
so
To find the total time to swim the whole race sum the time in the first half plus the time in second half
[tex](27.8+30.12)=57.92\ seconds[/tex]
therefore
the answer is
[tex]57.92\ seconds[/tex]
By adding the two given times, we will see that she completes the race in 57.92 seconds.
How to find the time in which she finishes the race?
We know that:
- She swims the first half on 27.8 seconds.
- She swims the second half on 30.12 seconds.
Then the time that it took to complete the whole race is just the sum of these two times, we will get:
Total time = 27.8 seconds + 30.12 seconds = 57.92 seconds.
We can conclude that Lily swims the whole race in 57.92 seconds.
