Question

If there is a video of 1 hour and i watch if in 1.25x speed how much time will it take for the video to end?​

Answer 1

Given : Normal video duration = 1 hour

To find : Video duration if the playing speed is 1.25x

Solution :

We can simply solve this mathematical problem by using the following mathematical process.

Now, video playing at normal speed means it is playing at 1x speed. From this we need to calculate the duration at 1.25x speed.

Normal video duration = 1 hour = 60 minutes

So,

Video duration at 1x speed = 60 minutes

Video duration at 1.25x speed = (60÷1.25) = 48 minutes

(This implies the video has been fast forwarded, which is absolutely correct. Because, 1.25 > 1)

Hence, the video duration at 1.25x speed is 48 minutes.

Answer 2

Answer:

Step-by-step explanation:

1 is the normal playback speed for a video.hence playing a video at 1.25x speed is equivalent to 1/4 times faster tahn reserved.

this will be chopping your watch time every single minute by a quarter

hence, for a normal playback speed=60min

                                  1.25x=?

1.25x60min/1 =75

75-60=15

difference,=15

thus,normal time -the difference-60-15

ans=45min.
