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

1 answer

To find out how many laps Nina can swim in one minute, we need to divide the total number of laps she can swim (4 laps) by the total amount of time it takes her to swim those laps (2 1/3 minutes).
First, convert the mixed number 2 1/3 into an improper fraction. The numerator of the fraction will be found by multiplying the whole number by the denominator and then adding the result to the numerator. In this case, 2 * 3 + 1 = 7.
So, 2 1/3 can be written as 7/3.
Next, divide the total number of laps (4 laps) by the total amount of time (7/3 minutes).
4 laps / 7/3 minutes = 4 laps * 3/7 minutes = (4*3)/(7*1) = 12/7.
Therefore, Nina can swim 12/7 laps in one minute.
