Question

из двух городов расстояние между которыми 7400 вылетели одновременно навстречу друг другу два самолета и встретились через 4 часа скорость одного самолета 950 км в час определите скорость второго самолета составьте обратную

Answer 1

Problem Analysis

We have two cities that are 7400 km apart. Two planes fly towards each other from these cities and meet after 4 hours. The speed of one plane is given as 950 km/h. We need to determine the speed of the second plane.

Solution

Let's assume the speed of the second plane is x km/h.

Since the two planes are flying towards each other, their combined speed is the sum of their individual speeds. Therefore, the combined speed of the two planes is 950 km/h + x km/h.

We know that the distance between the two cities is 7400 km and the time it takes for the planes to meet is 4 hours. We can use the formula distance = speed × time to set up an equation:

7400 km = (950 km/h + x km/h) × 4 hours

To solve for x, we can rearrange the equation:

7400 km = (950 km/h + x km/h) × 4 hours

7400 km = 3800 km/h + 4x km/h

7400 km - 3800 km/h = 4x km/h

3600 km = 4x km/h

Now, we can solve for x by dividing both sides of the equation by 4:

x = 3600 km / 4

x = 900 km/h

Therefore, the speed of the second plane is 900 km/h.

Answer

The speed of the second plane is 900 km/h.
