Question

Арасы 880 км болатын екі қаладан бір уақытта бір-біріне қарама қарсы бағытта екі пойыз жолға шықты. бірінші пойыздың жылдамдығы 50 км/сағ, ал екінші пойыздың жылдамдығы 60 км/сағ.пойыздар неше сағаттан кейін кездесті

Answer 1

50+60=110 км/час  скорость сближения поездов                                                        880:110=8часов                                                                                                          Ответ: Через 8 часов поезда встретятся

Answer 2

Problem Analysis

Two trains start from different cities and travel towards each other. The first train has a speed of 50 km/h, while the second train has a speed of 60 km/h. We need to determine how many hours it will take for the trains to meet.

Solution

To solve this problem, we can use the formula: time = distance / speed.

Let's assume that the time it takes for the trains to meet is 't' hours.

The distance traveled by the first train can be calculated as the product of its speed and time: distance1 = speed1 * t.

Similarly, the distance traveled by the second train can be calculated as: distance2 = speed2 * t.

Since the total distance traveled by both trains is equal to the total distance between the two cities (880 km), we can write the equation: distance1 + distance2 = 880.

Substituting the values of distance1 and distance2, we get: speed1 * t + speed2 * t = 880.

Simplifying the equation, we have: (speed1 + speed2) * t = 880.

Now, we can solve for 't' by dividing both sides of the equation by the sum of the speeds: t = 880 / (speed1 + speed2).

Let's substitute the given values into the equation to find the value of 't'.

Given: - Speed of the first train (speed1) = 50 km/h - Speed of the second train (speed2) = 60 km/h

Substituting these values into the equation, we get: t = 880 / (50 + 60).

Calculating the value of 't', we have: t = 880 / 110 = 8.

Therefore, it will take 8 hours for the trains to meet.

Answer

The two trains will meet after 8 hours of traveling.
