Answer 1

Problem Statement

Two pedestrians start walking towards each other from two villages simultaneously. The distance between the villages is 18 km. The first pedestrian walks at a speed of 4 km/h, while the second pedestrian walks at a speed of 2 km/h. How many hours will it take for them to meet?

Solution

To find the time it takes for the two pedestrians to meet, we can use the formula:

Time = Distance / Relative Speed

The relative speed is the sum of the speeds of the two pedestrians. Let's calculate the time it takes for them to meet.

Distance = 18 km

Relative Speed = 4 km/h + 2 km/h = 6 km/h

Time = 18 km / 6 km/h = 3 hours

Therefore, it will take them 3 hours to meet.
