Question

Грузовая машина может доехать с одного пункта В другой за 9 часов а легковая машина за 6 часов через сколько часов они встретятся если выйдут Из двух пунктов Одновременно навстречу друг другу

Answer 1

9÷2=4.5
6÷2=3
4,5-3=1,5

Answer 2

Problem Analysis

We are given that a truck can travel from point A to point B in 9 hours, while a car can travel the same distance in 6 hours. We need to determine at what time they will meet if they start simultaneously from two different points.

Solution

To solve this problem, we can use the concept of relative speed. The relative speed between the truck and the car is the sum of their individual speeds. Let's assume the distance between the two points is D.

The speed of the truck is D/9 (distance divided by time) and the speed of the car is D/6. The relative speed between the two vehicles is (D/9) + (D/6) = (2D + 3D)/18 = 5D/18.

To find the time it takes for the two vehicles to meet, we can divide the distance between the two points (D) by their relative speed (5D/18). This gives us the equation:

Time = Distance / Relative Speed

Substituting the values, we get:

Time = D / (5D/18) = 18/5 hours = 3.6 hours

Therefore, the truck and the car will meet after 3.6 hours.

Answer

If the truck and the car start simultaneously from two different points, they will meet after 3.6 hours.
