7. (10 points) During the landing process of Chang'e-3, the segment from 2.4 kilometers above the lunar surface to 100 meters above the lunar surface is called the approach segment. Figures 1 and 2 are screenshots of the video footage at 2.4 kilometers and 100 meters above the lunar surface, respectively. The time taken by Chang'e-3 during the approach segment is $\qquad$ seconds (The time notation in the video: 30:28/2:10:48 indicates

the total video duration is 2 hours 10 minutes 48 seconds, and it is currently playing at 30 minutes 28 seconds).
【Analysis】According to the data given in the question, the approach segment is from 45 minutes and 39 seconds to 47 minutes and 33 seconds of the video. By subtracting 45 minutes and 39 seconds from 47 minutes and 33 seconds, we can find out how long the approach segment lasts.

【Solution】Solution: 47 minutes and 33 seconds - 45 minutes and 39 seconds = 1 minute and 54 seconds = 114 seconds
Answer: The time that Chang'e-3 spent in the approach segment is 114 seconds.
Therefore, the answer is: 114.
