Question

On the first day of shooting a movie, a director uses 30% of a film reel. The strip of film used was 90 meters long. What is the standard length on a film reel? * O 200 O 100 O 300 O 400

Answer 1

300metres

Step-by-step explanation:

Let the standard length of the film reel be x

Percentage used = 30%

Length og strip film used = 90m

To get x, we will use the expression

30% of x = 90

0.3x = 90

x = 90/0.3

x = 300

Hence the the standard length on a film reel is 300metres
