Answers

Answer 1

Answer:

Answer: 90 meters strip of film was used.

Step-by-step explanation:

Since we have given that

Standard Length of film reel = 300 meters

On the first day of shooting a movie,

Percentage of the film on the reel is used by a director = 30%

So, Length of strip of film that was used is given by

$(30)/(100)* 300\n\n=90\ meters$

Hence, 90 meters strip of film was used.

= 30/100 * 300

= 30 * 3

= 90

Film used = 90 meters.
