In general, a high school students take about 5-7 classes in one year. Each class represents about one hour a day plus any required homework. In a homeschool, that means math and English make take a bit longer than an hour - my children did some of that in the evening.
In high school, my children worked from 8am until about 3 or 4pm each day. One day a week they worked much shorter hours on required subjects, but they were still busy doing things that I put on their high school transcript - sports teams, working at their job, or learning for fun with Delight Direct Learning.
