Problem Analysis

In this problem, we are given that two friends, Lisa and Rita, are traveling on a train to the countryside. Lisa notices that the return trains from the countryside pass by every 6 minutes. We are asked to determine how many trains arrive in the city within one hour if the speeds of the trains in both directions are the same.

Solution

To solve this problem, we need to calculate the number of trains that arrive in the city within one hour. Since the return trains pass by every 6 minutes, we can calculate the number of trains that arrive in one hour by dividing 60 minutes by 6 minutes.

Let's calculate the number of trains that arrive in one hour:

Step 1: Calculate the number of trains that arrive in one hour by dividing 60 minutes by 6 minutes:

60 minutes / 6 minutes = 10 trains

Therefore, if the speeds of the trains in both directions are the same, 10 trains will arrive in the city within one hour.

Answer

If the speeds of the trains in both directions are the same, 10 trains will arrive in the city within one hour.
