Since June has 30 days, halfway is 1/2*30 = <<1/2*30=15>>15

The total number of video hours halfway through June is 10*15 = <<10*15=150>>150

When she doubled the number of video hours, the total per day became 10*2 = <<10*2=20>>20

The total number of video hours for the remaining days is 15*20 = <<15*20=300>>300

The total number of video hours for the whole month is 300+150 = <<300+150=450>>450
