Answer:
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.
