Problem Analysis

We are given that the distance between a city and a village along a highway is 180 km. A truck and a bus start simultaneously from these cities towards each other. The truck has a speed of 40 km/h, and the bus has a speed of 50 km/h. We need to determine how many hours it will take for them to meet.

Solution

To solve this problem, we can use the formula:

Time = Distance / Speed

Let's calculate the time it will take for the truck and the bus to meet.

The total distance they need to cover is 180 km. Since they are traveling towards each other, the relative speed at which they are approaching each other is the sum of their speeds, which is 40 km/h + 50 km/h = 90 km/h.

Using the formula, we can calculate the time it will take for them to meet:

Time = Distance / Speed = 180 km / 90 km/h = 2 hours

Therefore, it will take them 2 hours to meet.

Answer

They will meet in 2 hours.
