a) write an expression to determine the number of frames in a movie.
b)using the running time of ET the extra-terrestrial, determine how many frames are in the movie.
*hint* et has a running time of 115 minutes or 6900 seconds

a) 24 t where t is the number of seconds the movie plays
b) 6900 X 24 = 165600 frames

There are 24 frames per second
So the total number of frames is 24 times the number of seconds
As an expression:
(number of frames) = 24 * (number of seconds)
Or if you prefer shorter variable names,
x = 24 * s
In the case of E.T.,
(number of frames) = 24 * 6900 = 165600
... give or take a few: Presuming the running time is rounded to the nearest minute, there could be a rounding error of up to 30 seconds, or 720 frames. However, the person who assigned you this problem probably doesn't want you to get that picky. :-)

Hey, it's a converstion problem! Sounds like it's from a test or homework. Remember that the conversion rate is 24 (frames/sec), and that time (or length of movies) can be measured in seconds. So if you multiplied the conversion rate by a duration of time, the dimension of "seconds" would cancel, and you would be left with a number of frames.

24s right? or maybe 1440 frames per minute to make it easier.
so if 115 Replaced minutes then it would be 1440 x 115 =165600 frames.
By the way.. My animations that i make are 24 fps so i am used to this sort of thing.

24x = y x = the amount of seconds in the movie. y = the total number of frames in the movie. Thus, according to your estimate of frames per second and your estimate of the length in seconds of the movie, there are 165,600 frames in the movie. Although, there are different fps rates for different movies.

I think that's the correct number. For some reason 24.5 keeps coming to mind, but that might just be the Alzheimers creeping in âº
Go look it up on the web.

24 * 3600 * length in hours = 165,600 frames
