Final answer:
To determine the time Alket reached school, calculate the time it took to cover each fraction of the distance and add them together. Alket reached school at 8:15 in the morning.
Step-by-step explanation:
To find out what time Alket reached school, we need to first determine the time it took him to walk 1/3 and 1/2 of the distance.
From the given information, we know that when Alket walks 1/3 of the way, it is 7:40, and when he walks 1/2 of the way, it is 7:45. This means that between 7:40 and 7:45, Alket covered 1/2 - 1/3 = 1/6 of the total distance.
Since the time between 7:40 and 7:45 is 5 minutes, and 1/6 of the total distance was covered during this time, we can calculate that Alket walks 5 minutes for each 1/6 of the distance. Therefore, it would take 5 minutes x 6 = 30 minutes for Alket to cover the entire distance.
So, Alket must have reached school at 7:45 + 30 minutes = 8:15 in the morning.
