1:55 you can change 2/5 of the day into minutes by multiplying it with 1440 minutes in a day hence you would get 576 minutes which is just a minute longer than 575 minutes
Just a tip: You can convert the time in hours to minutes by multiplying by 60. So in the question about whether 2/5 of a day or 575min is longer you do 2/5x24 and get 6hrs37mins. Pressing x60 then = returns 576 which means you don't have to convert 575 into hrs and minutes. Likewise for the last example, multiply 2hrs 4mins by 60 if you want that time in minutes. PS: Did you realise that there's a typo for average at 5:04?
