Answer :

Answer:

3 laps per minute.

Step-by-step explanation:

We can find the laps per minute that Hayley swims by dividing the total number of laps by the total time spent swimming.

Here's how to calculate it:

Laps per minute:

Laps per minute = Total laps / Total time (minutes)

Laps per minute = 45 laps / 30 minutes

Simplify:

Laps per minute = 3 laps/minute (since 45 divided by 30 is 1.5, which is the same as 3 divided by 1)

Therefore, Hayley swims 3 laps per minute.
