Question

A motion picture camera at normal speed takes 24 pictures per second. How many pictures are in a movie that is 90 minutes long? (Hint 1min = 60 seconds)

Answer 1

P = 24 (90 x 60)
P = 24 x 5400
P = 129600

129600 pictures are taken during a 90 minute movie.

Answer 2

24 × 60 = 1,440
1,440 × 90 = 129,600

There are 129,600 pictures in a movie that is 90 minutes long.
