Answer 1

Problem Analysis

We are given that two pedestrians start walking towards each other from two villages. The first pedestrian has a speed of 6.7 kilometers per hour, and the second pedestrian has a speed of 4.6 kilometers per hour. After 2 hours and 30 minutes, they meet. We need to find the distance between the villages.

Calculation

To find the distance between the villages, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled by each pedestrian and then find the total distance between the villages.

The first pedestrian's speed is 6.7 kilometers per hour, and the time is 2 hours and 30 minutes. We need to convert the time to hours by dividing it by 60:

Time = 2 hours + 30 minutes = 2 + 30/60 = 2.5 hours

Now we can calculate the distance traveled by the first pedestrian:

Distance1 = Speed1 × Time = 6.7 km/h × 2.5 h = 16.75 km

Similarly, for the second pedestrian, the speed is 4.6 kilometers per hour, and the time is 2.5 hours. Let's calculate the distance traveled by the second pedestrian:

Distance2 = Speed2 × Time = 4.6 km/h × 2.5 h = 11.5 km

To find the total distance between the villages, we can add the distances traveled by both pedestrians:

Total Distance = Distance1 + Distance2 = 16.75 km + 11.5 km = 28.25 km

Answer

The distance between the villages is 28.25 kilometers.
