Answer: 40laps
Stepbystep explanation:
Sebastian swam 45minutes per day.
If she swam 5days a week, this is equivalent to Sebastian swimming 60days in 12weeks.
If Sebastian swam 45minutes in a day, she must have swam for (45×60)minutes in 60days which is equivalent to 2700minutes
Converting 2700minutes to hours;
60minutes = 1hour
2700minutes = x
x = 2700/60
x = 45hours
Since sebastian swam 1800laps in that 12weeks in 45hours, her average rate lap per hour can be calculated thus;
1800laps = 45hours
X laps = 1hour
30 × X = 1800
X = 1800/45
X = 40laps
This shows that Sebastian swam 40laps in one hour in average.
