Analysis and Solution

To determine who will arrive earlier at the meeting place and by how many minutes, we need to compare the perceived time difference for each person.

According to the information provided, Valya's clock is running 7 minutes behind, but she believes it is 3 minutes fast. On the other hand, Vanya's clock is running 2 minutes fast, but he thinks it is 8 minutes behind.

Let's calculate the actual time difference for each person:

- Valya's actual time difference: 7 minutes behind - 3 minutes fast = 4 minutes behind. - Vanya's actual time difference: 2 minutes fast - 8 minutes behind = 10 minutes behind.

Now, let's consider the agreed meeting time of 5 o'clock yesterday. To determine who will arrive earlier, we need to subtract the actual time difference for each person from the agreed meeting time.

- Valya's arrival time: 5 o'clock - 4 minutes = 4:56 PM. - Vanya's arrival time: 5 o'clock - 10 minutes = 4:50 PM.

Therefore, Vanya will arrive earlier at the meeting place, by 6 minutes.

Note: The calculations above assume that the clocks are not adjusted during the day and that the time difference remains constant.

Answer

Vanya will arrive earlier at the meeting place, by 6 minutes.
