After a long while, Mr. Zhang said solemnly, "Immediately compare the time this person appeared at the entrance of the shopping street with the time at the campus entrance."
"Alright!"
Right after, the young officer moved the mouse and stretched the progress bar.
After observing carefully, he turned his head and said, "Mr. Zhang, the time has been confirmed."
"Li Lan appeared at the commercial street entrance of the campus at 2:07 PM, and the time at the school gate entrance was 2:20 PM."
Mr. Zhang mumbled to himself, "A walking time of 13 minutes in between."
"How long is the distance on that road?"
At that moment, the young officer pulled up the flat map.
He responded, "The distance from the entrance of the shopping street to the campus entrance is 1.1 kilometers."
At this time, Jiang An said, "According to our normal walking speed, young people walk about 1.5 meters per second, clearly less than 13 minutes."
