Question

Each frame in an animated film take at least one hour to draw. When projected, 35-millimeter film runs at 24 frames per second. A 2.5 hour movie has about 216,000 frames. How many hours would it take to draw the frames needed for a 1.5 hour animated film?

Answer 1

It would take `129600` hours to draw the frames needed for a `1.5` hour animated film.

Explanation:

We can solve this question using proportions.

Let `x` be the number of frames in a `1.5` hour film.

`2.5/216000 = 1.5/x`

By cross-multiplication, we get

`1.5 * 216000 = 2.5x`

`324000 = 2.5x`

`x = 324000/2.5`

`x = 129600`

Since it takes one hour to draw each frame, it would take `129600 xx 1` hours, which is just `129600` hours, to draw the frames needed for a `1.5` hour animated film.
