Answer 2

4х60+5х2+6Х60+15х2=
=245х2+375х2=
=490+750=1240

Answer 3

Let's begin by converting the hours and minutes into minutes, so we can perform the multiplication more easily:

4 hours and 5 minutes = (4 x 60) + 5 = 245 minutes 6 hours and 15 minutes = (6 x 60) + 15 = 375 minutes

Now we can substitute these values into the equation:

4часа 5мин × 2 + 6ч15мин × 2 = 245 × 2 + 375 × 2

Simplifying the right side of the equation:

245 × 2 + 375 × 2 = 490 + 750 = 1240

Therefore, the final answer is:

4часа 5мин × 2 + 6ч15мин × 2 = 1240 минут = 20 часов 40 минут
