Problem Analysis

We are given that two tourists start walking towards each other from two different cities, City 1 and City 2, which are 36 km apart. The first tourist walks at a speed of 1 km in 15 minutes, while the second tourist walks at a speed of 1 km in 12 minutes. We need to find out how long it will take for them to meet.

Solution

To solve this problem, we can calculate the time it takes for each tourist to cover the distance between the cities and then find the total time it takes for them to meet.

Let's calculate the time it takes for the first tourist to cover the distance between the cities: - Speed of the first tourist = 1 km / 15 minutes = 1/15 km/minute - Distance between the cities = 36 km - Time taken by the first tourist = Distance / Speed = 36 km / (1/15 km/minute) = 540 minutes

Now, let's calculate the time it takes for the second tourist to cover the distance between the cities: - Speed of the second tourist = 1 km / 12 minutes = 1/12 km/minute - Distance between the cities = 36 km - Time taken by the second tourist = Distance / Speed = 36 km / (1/12 km/minute) = 432 minutes

To find the total time it takes for them to meet, we can add the times taken by each tourist: Total time = Time taken by the first tourist + Time taken by the second tourist = 540 minutes + 432 minutes = 972 minutes

Therefore, it will take them 972 minutes to meet.

Answer

It will take the two tourists 972 minutes to meet.
