Michelle walks 1/4 hour everyday of the week Sandra walks 2/4 hour per day but olny on weekdays Monday to Friday both Michelle and Sandra continue their routine for 9 weeks who walked the most

Answer 1

Michelle walks 1/4 hour per day for 7 days a week, so she walks a total of 1/4 * 7 = 1.75 hours per week.
Sandra walks 2/4 hour per day for 5 days a week, so she walks a total of 2/4 * 5 = 2.5 hours per week.

Over 9 weeks, Michelle walks a total of 9 * 1.75 = 15.75 hours.
Over 9 weeks, Sandra walks a total of 9 * 2.5 = 22.5 hours.

Therefore, Sandra walked more than Michelle over the 9-week period.
