Question

7ч48мин56сек×18 сколько это будет?

Answer 1

56*18=1008с:16,8=16мин 8сек,

48*18=864мин:60=14ч. 4мин.

7*18=126ч

126+14=140ч.

16+4=20мин

7 ч. 48 мин. 56 сек. * 18= 140 ч. 20мин. 8 сек.

Answer 2

To calculate the product of 7 hours 48 minutes 56 seconds and 18, first, we need to convert the hours, minutes, and seconds to a single unit (e.g., seconds) and then perform the multiplication.

1 hour is equal to 60 minutes, and 1 minute is equal to 60 seconds. So, we can convert the given time to seconds as follows:

7 hours = 7 * 60 * 60 = 25,200 seconds 48 minutes = 48 * 60 = 2,880 seconds Total time in seconds = 25,200 + 2,880 + 56 = 28,136 seconds

Now, we can multiply this total by 18:

28,136 seconds * 18 = 506,448 seconds

To express the result in hours, minutes, and seconds again:

506,448 seconds ÷ 60 seconds/minute ÷ 60 minutes/hour = 140 hours and some remainder.

To find the remaining minutes, we take the remainder after dividing by 60 minutes:

506,448 seconds ÷ 60 seconds/minute = 8,440 minutes and some remainder.

Finally, to find the remaining seconds:

Remainder = 8,440 minutes * 60 seconds/minute = 504 seconds.

So, the result is approximately 140 hours, 8 minutes, and 504 seconds.
