Problem Analysis

We have two trucks traveling towards each other from two different cities. The distance between the cities is 360 km. The speed of one truck is 36 km/h, which is 2/3 of the speed of the other truck. We need to find out how much time it will take for the trucks to meet.

Solution

Let's assume the speed of the second truck is x km/h. According to the problem, the speed of the first truck is 2/3 of the speed of the second truck. Therefore, the speed of the first truck is (2/3) * x km/h.

We can use the formula time = distance / speed to find the time it takes for the trucks to meet. The total distance they need to cover is 360 km.

The time taken by the first truck to cover the distance is given by: time1 = distance / speed1 = 360 km / ((2/3) * x km/h)

The time taken by the second truck to cover the distance is given by: time2 = distance / speed2 = 360 km / x km/h

Since the trucks are traveling towards each other, the total time taken for them to meet is the sum of time1 and time2: total time = time1 + time2

Let's calculate the total time taken for the trucks to meet.

Calculation

Substituting the values into the equations, we have: time1 = 360 km / ((2/3) * x km/h) time2 = 360 km / x km/h

The total time taken for the trucks to meet is: total time = time1 + time2

Answer

The trucks will meet in the calculated total time.
