Solve the following problem: Rosalie exercises for ⅖ of an hour every morning.
How much time does she spend exercising in a week? Convert the answer to a mixed number.
To find the total time Rosalie spends exercising in a week, we need to find the product of the time she exercises each morning by the number of days in a week.
⅖ of an hour is equal to (2/5) * (60 minutes/hour) = 24 minutes.
There are 7 days in a week.
So, the total time Rosalie spends exercising in a week is 24 minutes/day * 7 days/week = 168 minutes/week.
To convert this to a mixed number, we divide the total minutes by 60 to get the number of hours and use the remainder as the minutes.
168 minutes = 2 hours + 48 minutes.
Therefore, Rosalie spends 2 and 48/60 hours exercising in a week.
