Question

Помогите решить задачу : вертолет за 2 часа пролетел 430км. сколько километров пролетит за 5ч самолет, если его скорость в 3 раза больше вертолета?

Answer 1

Скорость вертолёта = 430/2 = 215 км/ч

Скорость самолётак = 215* 3 = 645 км/ч

За 5 часов самолёт пролетит 645*3 = 1935 км.

Answer 2

430:2•3•5=3225 вот решение , удачи

Answer 3

Problem Analysis

To solve this problem, we need to find the distance that an airplane will travel in 5 hours, given that its speed is 3 times greater than that of a helicopter. We are given that the helicopter traveled 430 km in 2 hours.

Solution

Let's start by finding the speed of the helicopter. We can do this by dividing the distance traveled by the time taken: Speed of the helicopter = Distance / Time = 430 km / 2 hours = 215 km/h.

Now, we know that the speed of the airplane is 3 times greater than the speed of the helicopter. Therefore, the speed of the airplane is: Speed of the airplane = 3 * Speed of the helicopter = 3 * 215 km/h = 645 km/h.

To find the distance traveled by the airplane in 5 hours, we can multiply the speed of the airplane by the time taken: Distance traveled by the airplane = Speed of the airplane * Time = 645 km/h * 5 hours = 3225 km.

Therefore, the airplane will travel 3225 km in 5 hours.

Conclusion

The airplane will travel 3225 km in 5 hours, given that its speed is 3 times greater than that of the helicopter, which traveled 430 km in 2 hours.
