Answer 3

Problem Analysis

Two pedestrians are walking towards each other from two different points, and we need to determine how long it will take for them to meet. We are given the distance between the two points (36 km) and the speeds of the pedestrians (4 km/h and 5 km/h).

Solution

To solve this problem, we can use the formula: time = distance / speed.

Let's calculate the time it takes for each pedestrian to cover the distance between the two points:

- For the first pedestrian, with a speed of 4 km/h: - Time taken = distance / speed = 36 km / 4 km/h = 9 hours

- For the second pedestrian, with a speed of 5 km/h: - Time taken = distance / speed = 36 km / 5 km/h = 7.2 hours

Since both pedestrians started at the same time, we need to find the time it takes for them to meet. We can do this by taking the average of the two times:

- Average time = (9 hours + 7.2 hours) / 2 = 8.1 hours

Therefore, the two pedestrians will meet after approximately 8.1 hours.

Answer

The two pedestrians will meet after approximately 8.1 hours.

Explanation

The first pedestrian, with a speed of 4 km/h, will take 9 hours to cover the distance of 36 km The second pedestrian, with a speed of 5 km/h, will take 7.2 hours to cover the same distance Taking the average of these two times, we find that the two pedestrians will meet after approximately 8.1 hours.
