Nina can swim 4 laps in 2 1/3 minutes at this rate how many laps can she swim in one minute

To find out how many laps Nina can swim in one minute, we need to find the reciprocal of 2 1/3 minutes.

To find the reciprocal, we invert the fraction: 2 1/3 becomes 3/7.

So, Nina can swim 3/7 laps in one minute.

To find out how many laps Nina can swim in one minute, you need to divide the total number of laps she can swim by the time it takes her to swim those laps.

In this case, Nina can swim 4 laps in 2 1/3 minutes. To make the calculation easier, let's convert the mixed number 2 1/3 into an improper fraction:

2 1/3 = (2 * 3 + 1) / 3 = 7/3

Now, divide the number of laps (4) by the time in minutes (7/3):

4 laps / (7/3 minutes) = 4 laps * (3/7 minutes) = 12/7 laps

Therefore, Nina can swim approximately 12/7 laps in one minute.

To find out how many laps Nina can swim in one minute, we can use the given information that she can swim 4 laps in 2 1/3 minutes.

Step 1: Convert the mixed number 2 1/3 to an improper fraction.
2 1/3 = (2 * 3 + 1)/3 = 7/3

Step 2: Calculate the lap-swimming rate per minute.
Rate per minute = Number of laps / Number of minutes
Rate per minute = 4 laps / 7/3 minutes

Step 3: Divide the number of laps by the number of minutes.
Rate per minute = 4 laps / 7/3 minutes
Rate per minute = 4 laps * 3/7 minutes
Rate per minute = 12 laps / 7 minutes

Therefore, Nina can swim approximately 12/7 laps in one minute.
