Bennie swims 6 laps in 4 1/2 minutes. what is the rate in minutes per lap

6 laps ... 4 1/2 = 9/2 minutes

1 lap ... x minutes = ?

If you would like to know what is the rate in minutes per lap, you can calculate this using the following steps:

6 * x = 9/2 * 1

6 * x = 9/2 / 6

x = 9/2 / 6

x = 9/12

x = 3/4 minute

The correct result would be 3/4 minute per lap.

6 laps = 4.5 minutes.

Now we need to set up a proportion to determine minutes per lap.

6/4.5 = 1/x

Cross multiply

6x = 4.5*1

6x = 4.5

6x/6 = 4.5/6

x = 0.75

It takes 0.75 minutes per lap.

Final answer: 0.75 minutes per lap
