Calculating Painting Time

To calculate the time it takes for 5 painters to paint 30 frames, we can use the given information that 10 painters can paint 60 frames in 120 minutes.

Let's calculate the time it takes for 1 painter to paint 1 frame: - 10 painters can paint 60 frames in 120 minutes, so 1 painter can paint 60 frames in 10 times the time, which is 1200 minutes. - Therefore, 1 painter can paint 1 frame in 1200 / 60 = 20 minutes.

Now, we can calculate the time it takes for 5 painters to paint 30 frames: - 5 painters working together will be 5 times faster than 1 painter, so they can paint 30 frames in 20 / 5 = 4 minutes.

So, 5 painters can paint 30 frames in 4 minutes.
