A tv commercial is filmed at 100 frames per second. If you played the commercial at 20 frames every second, how long would the commercial play? 5 seconds 2000 seconds 120 seconds

Sagot :

you reproduce the commercial at 20 frames every second, to find how many seconds do you need to reproduce 100 frames, we can use the next proportion:

[tex]\frac{20\text{ frames}}{100\text{ frames}}=\frac{1\text{ second}}{x\text{ seconds}}[/tex]

Solving for x:

[tex]\begin{gathered} 20\cdot x=1\cdot100 \\ x=\frac{100}{20} \\ x=5\text{ seconds} \end{gathered}[/tex]
