Solve the following problem: Rosalie exercises for 25 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 amount of time Rosalie spends exercising in a week, we need to multiply the amount of time she spends exercising each morning (25 of an hour) by the number of mornings in a week.
There are 7 days in a week, so there are 7 mornings in a week.
25 of an hour x 7 mornings = 175 of an hour.
To convert this to a mixed number, we divide 175 by 60 to get the number of hours and minutes.
175 รท 60 = 2 remainder 55.
So, Rosalie spends 2 hours and 55 minutes exercising in a week.
