Question 701378: On a normal day, I can walk from my house to school in three quarters of an hour. The return trip takes me the same amount of time. My mom, driving our car, covers that distance in about a quarter of the time that it takes me. If I go to school five days a week and there are thirty-seven weeks in the school year, how many hours would I save every year if my mom agreed to drive me to and from school? Give your answer as a mixed number.

Mom drives the car home in a quarter of the time it takes you to walk, three quarters of an hour. so she takes
%281%2F4%29%2A%283%2F4%29=3%2F16 of an hour to drive.
this will save
3%2F4-3%2F16=9%2F16 of an hour every day.
to find the total time saved over the school year
%289%2F16%29%2A37%2A5=1041%2F16 hours
(one hundred and four and one sixteenth hours)
