A developer wants to use a frame rate of 30 frames per second for a very bandwidth intense video display of 20 second length. How many frames will be played in the video? (You do not need to include the units. You only need to enter your answer as a number.)

600 frames will be played in the video.

Step-by-step explanation:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three. Remember that proportionality is a constant relationship or ratio between different magnitudes.

If the relationship between the magnitudes is direct, the following formula must be followed:

a ⇒ b

c ⇒ x

where a, b, and c are the known values and x is the unknown value you want to calculate. The way to apply the rule of three is:

The way to apply the rule of three in this case is: if the frame rate indicates that 30 frames are played in 1 second, in 20 seconds how many frames will be played in the video?

1 second ⇒ 30 frames

20 seconds ⇒ x

So:

x=600 frames

600 frames will be played in the video.
