Question

You need to show the steps in how you did it and the answer.

Answer 1

First let determine how many hours Sebastian swam.

 

He swam 45 minutes each day, 5 days a week, for 12 weeks.

 

t = 45 * 5 * 12  where total in minutes Sebastian swam

t = 2700 minutes

 

To calculate the average rate in laps per hour, we need to know t in hours.

There are 60 minutes in 1 hour, so T (in hours) = t(in minutes) /60

 

T = 2700 / 60

T = 45hours

 

Now we can determine the average rate in laps per hour

 

We know that Sebastian swam 45 hours.

We also know that Sebastian swam 1,800 laps.

 

The rate is determined by dividing the number of laps by the time swam in hours.

 

Rate = 1800 / 45

Rate = 40 laps per hour

 

Sebastian swam at an average rate of 40 laps per hour.
