Umnica [9.8K]
<span>The video last for about 6.44 minutes. Rounded to the nearest minutes
=> So let’s simplify the given equation
=> 6.44 minutes in where 6 = minutes, 44 = seconds.
Now, we have our minute’s value which is 6, let us start the rounding
=> 6.44, the number that follows the 6 is a decimal number which is 4.
4 is below 5, so we need to follow the rounding rule. This will round down.
=> 6 minutes
Therefore, the video lasts for about 6 minutes.
