Question

два самолёта летели с одинаковой средней скоростью. один самолёт был в воздухе 3ч, другой - 5ч и пролетел на 1600км больше,чем первый.поставь вопрос и реши задачу.помогите пожалуйста...

Answer 1

Вопрос- найти расстояние которое пролетели оба самолёта
1) 5-3=2 (разница между 2 и 1 самолётом)
2) 1600 : 2 = 800 км/ч (скорость обоих самолётов)
3) 800 * 3 = 2400 км ( расстояние 1 самолёта)
4) 800 * 5 = 4000 км (расстояние 2 самолёта)

для проверки 4000 - 2400 = 1600 км

Answer 2

Problem Statement:

Two airplanes flew at the same average speed. One airplane was in the air for 3 hours, while the other was in the air for 5 hours and flew 1600 km farther than the first airplane. We need to find the average speed of the airplanes and the distance each airplane traveled.

Solution:

Let's break down the problem and solve it step by step.

Step 1: Define the variables: Let's assume: - The average speed of both airplanes is x km/h. - The distance traveled by the first airplane is d km. - The distance traveled by the second airplane is d + 1600 km.

Step 2: Calculate the distances traveled by each airplane: Using the formula distance = speed × time, we can calculate the distances traveled by each airplane: - Distance traveled by the first airplane = x × 3 km. - Distance traveled by the second airplane = x × 5 km.

Step 3: Set up the equation: Since the second airplane flew 1600 km farther than the first airplane, we can set up the equation: x × 5 = x × 3 + 1600.

Step 4: Solve the equation: Let's solve the equation to find the value of x: - x × 5 = x × 3 + 1600 - 5x = 3x + 1600 - 2x = 1600 - x = 800

Step 5: Calculate the distances traveled by each airplane: Now that we have the value of x, we can calculate the distances traveled by each airplane: - Distance traveled by the first airplane = 800 × 3 = 2400 km. - Distance traveled by the second airplane = 800 × 5 = 4000 km.

Answer:

The average speed of both airplanes is 800 km/h. The first airplane traveled a distance of 2400 km, while the second airplane traveled a distance of 4000 km.
