Laura can swim 2 laps in the local swimming pool every 1.5 minutes . At this rate, how many minutes does Laura need to swim 12 laps? square

To find out how many minutes Laura needs to swim 12 laps, we first need to determine her swimming rate in laps per minute. Laura can swim 2 laps in 1.5 minutes, so her rate is:<br /><br />\[<br />\text{Rate} = \frac{2 \text{ laps}}{1.5 \text{ minutes}} = \frac{2}{1.5} = \frac{4}{3} \text{ laps per minute}<br />\]<br /><br />Next, we need to find out how many minutes it takes for Laura to swim 12 laps. We use the rate we just calculated:<br /><br />\[<br />\text{Time} = \frac{\text{Total laps}}{\text{Rate}} = \frac{12 \text{ laps}}{\frac{4}{3} \text{ laps per minute}} = 12 \times \frac{3}{4} = 12 \times 0.75 = 9 \text{ minutes}<br />\]<br /><br />Therefore, Laura needs to swim for 9 minutes to complete 12 laps.
