An athlete training for the olympics women's each lap for a 4 lap race in the following times: 54.73, 54.56, and 54.54 seconds. what is the total time it takes her to swim the four laps.

The total time it takes her to swim the four laps is 3.65 minutes.

Step-by-step explanation:

Here, according to the given data:

The time taken to complete 1st lap =  54.73 seconds

The time taken to complete 2nd lap =  54.56 seconds

The time taken to complete 3rd lap =  54.32 seconds

The time taken to complete 4th lap =  54.54 seconds

Now, the TOTAL TIME taken to swim all 4 laps  = SUM OF ALL 4 TIMES

= (54.73  + 54.56 + 54.32 + 54.54) seconds

= 219.35 Seconds

Now, 60 seconds = 1 minute

⇒ 1 seconds  = 1/60 minute

⇒219.35 seconds = 219.27 x (1/60) minutes = 3.6558  minutes

Hence, the total time it takes her to swim the four laps is 3.65 minutes.
