Megan's video is 6 minutes, 13 seconds long. This is calculated using simple arithmetic.
Reall that 60 seconds make one minute. Since most of the details are given in seconds, we add all the seconds together and divide by 60 to get the length of time in minutes.
That is:
12 + 142 + 99 = 253 seconds.
253/60 = 4.21666666667
Hence the total length of time is
2 + 4.21666666667 = 6.21666666667
We cannot afford to have decimals so to get the correct balance in seconds we multiply 0.21666666667 by 60 to get the amount in seconds.
0.21666666667 x 60 = 13.0000000002
Hence the total length of Megan's Video is
6 minutes, 13 seconds.
