Question

d) A movie time was 2hours. 10% of the time was taken advertisement. How long was the actual movie? ​

Answer 1

Answer:

108 minutes

Step-by-step explanation:

Lets say that M+A is the time of the movie and the advertisement, so;

M+A = 2

And we know that 10% of that time is advertisement, mathematically that is:

A = 0,1*2

So replacing the second equation in the first one we have;

M + 0,1*2 = 2

M = 2-0,1*2 = 1,8 hours

We can convert hours into minutes multiplying by 60

1,8h*60min/h = 108min

Answer 2

Answer:

1.8 hours ( 108 minutes)

Step-by-step explanation:

10% of 2 hours is 12 minutes

120 minutes - 12 minutes = 108 minutes
