There are 7 Days and 7 hours in 175 hours
175 hours is about 7 1/2 days
2.9167 hours.

Since there are about 175 school days in a year, it would be 1,400 hours, divided by 24, is about 60 days worth of school hours.
175 miles at 65 miles per hour would be 2.69 hours
Assuming each month is going to be 30 days, 175 days would be around 5- 6 months.
60 minutes = 1 hour so 175 minutes = 175/60 = 2.91666... hours
Wisconsin has a set number of minutes/hours--I don't know what that is ("x"). Then there are days--a separate issue. (Public) schools must be in session for 175 days, and must include "x" number of hours. Most public school districts schedule 181+ days, but some take those 181 student days and lengthen them but have fewer days to allow for professional development for teachers. This is fine until snow days or cold days bring a district's total under 175, in which case districts must make up the days (even if they have enough hours).

There are 175 days in 25 weeks.
The amount of time is between 175 and 180 days of school and/or between 900 and 1,000 hours of instructional time per year, depending on the grade level.
