To find out how many laps Andre swims per minute, we divide the total number of laps by the total time in minutes:

$\text{Laps per minute} = \frac{\text{Total laps}}{\text{Total time in minutes}} = \frac{5 \text{ laps}}{4 \text{ minutes}} = 1.25 \text{ laps per minute}$

So, Andre swims 1.25 laps per minute.

Tip: When solving rate problems, always remember to divide the quantity by time for a "per time unit" calculation.
