75 yards is 68.58m so to convert 8.3s for 75 yards to 70m:
= 70/68.58 x 8.3
= 8.47s
To convert 12 minutes and 47 seconds into milliseconds, we first need to convert the minutes into seconds. There are 60 seconds in a minute, so 12 minutes is equal to 12 x 60 = 720 seconds. Adding the remaining 47 seconds gives us a total of 720 + 47 = 767 seconds. To convert seconds to milliseconds, we multiply by 1000, so 767 seconds is equal to 767 x 1000 = 767,000 milliseconds. Therefore, holding his breath for 12 minutes and 47 seconds is equivalent to 767,000 milliseconds.
