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.
