Amovie is 1 7/8 hours long. after 45 minutes, how much of the movie is left?

The movie will be left for:

                     67.5 minutes                        

It is given that:

A movie is 1 7/8 hours long.

i.e.

A movie is: 15/8 hours long.

( Since,

which is nothing but 112.5 minutes  )

Now, the amount of movie which will be left over is:

Total time of the movie- 45 minutes

=  112.5-45

= 67.5 minutes

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e
