Question

(63с•5+1 мин3с•6)+4ч180с-7200с=

Answer 1

Должно получится 9.450сек и.е. 157,5мин.

Answer 2

Let's break down the given expression step by step:

63с•5 represents 63 multiplied by 5 seconds, which is equal to 315 seconds.

1 мин3с•6 represents 1 minute multiplied by 3 multiplied by 6 seconds, which is equal to 18 seconds.

63с•5 + 1 мин3с•6 can be simplified as 315 seconds + 18 seconds, which equals 333 seconds.

Now let's continue evaluating the remaining part of the expression:

4ч180с represents 4 hours multiplied by 180 seconds. Since there are 60 seconds in a minute and 60 minutes in an hour, we can convert 180 seconds to minutes by dividing it by 60. So, 180 seconds is equal to 3 minutes.

4ч180с can be rewritten as 4 hours multiplied by 3 minutes, which is equal to 12 minutes.

Finally, we subtract 7200 seconds from the previously calculated result:

333 seconds + 12 minutes can be converted to seconds by multiplying 12 minutes by 60 (since there are 60 seconds in a minute), which gives us 720 seconds.

Now we can subtract 7200 seconds from 333 seconds + 720 seconds:

333 seconds + 720 seconds - 7200 seconds equals -6147 seconds.

Therefore, the simplified result of the expression (63с•5+1 мин3с•6)+4ч180с-7200с is -6147 seconds.
