the average would be 25 minutes. Is that the question?
If your current homework takes an hour - more homework would take more than an hour. If your current homework takes 5 minutes - more homework might take less than an hour. It depends on current homework work load.

One Direction's 'WHAT MAKES YOU BEAUTIFUL" is exactly 3 minutes 18 seconds long.
He has 2 hours and 25 minutes to do his homework. But maybe he will need to pack and get all his clothes and everything ready for the sleepover which will take about 15 minutes. So maybe about 2 hours and 10 minutes. But unles he has really really hard homework then he won't need all that time so I think he has plenty of time! But next time work these type of things out for yourself cause it was quite simple!

It will take him 7 hours 30 minutes.
