Problem Analysis

Sveta has recorded cartoons on a disk, and the disk has enough memory for 3 hours of content. She has already recorded a 40-minute cartoon on the disk. The question is whether she can record 5 more cartoons, each lasting 30 minutes, on the same disk.

Solution

To determine if Sveta can record 5 more cartoons on the disk, we need to calculate the total time the cartoons will take and compare it to the remaining available time on the disk.

1. Calculate the total time of the 5 cartoons: - Each cartoon lasts 30 minutes. - Sveta wants to record 5 cartoons. - Therefore, the total time of the 5 cartoons is 30 minutes x 5 = 150 minutes.

2. Calculate the remaining available time on the disk: - The disk initially had enough memory for 3 hours of content, which is 3 hours x 60 minutes = 180 minutes. - Sveta has already recorded a 40-minute cartoon on the disk. - Therefore, the remaining available time on the disk is 180 minutes - 40 minutes = 140 minutes.

3. Compare the total time of the 5 cartoons to the remaining available time on the disk: - The total time of the 5 cartoons is 150 minutes. - The remaining available time on the disk is 140 minutes. - Since the total time of the 5 cartoons is greater than the remaining available time on the disk, Sveta cannot record 5 more cartoons on the same disk.

Therefore, Sveta will not be able to record 5 more cartoons, each lasting 30 minutes, on the same disk.

Conclusion

Sveta will not be able to record 5 more cartoons, each lasting 30 minutes, on the same disk because the total time of the 5 cartoons (150 minutes) exceeds the remaining available time on the disk (140 minutes).
