7 hours and 48 minutes

Explanation:

let us recall the following from the question,

The Senator Kennedy's initiative proposal of extending the school day by = 30% of radical increase

The school day hour is = 6 hour

Then

30% of 6 hour = 30/100 x 6 = 1.8 hours, which is the extended school hour

The total hour = 6 hours + 1.8 hours = 7.8 hours

Therefore,

8 hours = 8/10 to minutes = 8/10 x 60 = 48 minutes

or 7.8/10 x 60 = 46.8 minutes

The total time = 7 hours and 48 minutes or 7 hours 46 minutes.
