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:

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.
