Question

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.

Answer 1

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

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.
