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?

we know that

1) Lily swims a -meter race

2) She swims the first half in seconds

3) She swims the second half in 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

therefore

the answer is

By adding the two given times, we will see that she completes the race in 57.92 seconds.

We know that:

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.

answer: check all that apply, where the options?
