lily swims a 100-meter race. she swims the first half in 27.8 seconds. she swims the second half in 30.12 seconds. how long does it take lily to swim the whole race?

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.
