Final answer:
Andre will swim 1.25 laps in 1 minute and it will take him 0.8 minutes to swim one lap.
Step-by-step explanation:
To find out how far Andre will go in 1 minute, we can set up a proportion using the information given. If it takes him 4 minutes to swim 5 laps, then his rate is 5 laps / 4 minutes, or 1.25 laps per minute. So in 1 minute, he would swim 1.25 laps.
To find out how long it will take him to swim one lap, we can set up another proportion. If he swims 5 laps in 4 minutes, then his rate is 5 laps / 4 minutes, or 1.25 laps per minute. So it will take him 1 minute / 1.25 laps per minute, or 0.8 minutes, to swim one lap.
