    Her swimming rate can either be written as 1.6 laps per (one) minute or as 0.625 minutes per lap = 37.5 seconds per (one) lap.

    In terms of number of laps per minute, the answer is

    20

    laps

    12.5

    minutes

    =

    1.6

    laps per minute.

    In terms of the number of minutes per lap, the answer is

    12.5

    minutes

    20

    laps

    =

    5

    8

    =

    0.625

    minutes per lap. This is the same as

    0.625

    min

    lap



    60

    The faster she goes, the more laps she can do in a minute and the fewer minutes (or seconds) it takes her to do one lap.
