Question

Пожалуйста помогите с задачей если вас не затруднит Из Москвы в Иркутск вылетел вертолёт. Через 16ч вслед за ним вылетел самолёт со скоростью 840км\ч.Вычисли скорость вертолёта, если известно, что в аэропорт Иркутска они прибыли одновременно, а расстояние от Москвы до Иркутска равно 4 200км

Answer 1

4200:840=5(ч) время самолёта в пути
16+5=21(ч) время вертолёта в пути
4200:21=200(км/ч) скорость вертолёта

Answer 2

Problem Analysis

To solve this problem, we need to find the speed of the helicopter. We know that the helicopter took off from Moscow to Irkutsk, and after 16 hours, a plane took off at a speed of 840 km/h. Both the helicopter and the plane arrived at the Irkutsk airport simultaneously. The distance between Moscow and Irkutsk is given as 4,200 km.

Solution

Let's assume the speed of the helicopter is v km/h.

We can use the formula: distance = speed × time.

For the helicopter, the distance traveled is 4,200 km, and the time taken is 16 hours.

So, we have the equation: 4,200 = v × 16.

Simplifying the equation, we get: v = 4,200 / 16.

Now, let's calculate the speed of the helicopter.

Calculation

Using the given values, we can calculate the speed of the helicopter as follows:

v = 4,200 / 16

Calculating the above expression, we find:

v ≈ 262.5 km/h

Therefore, the speed of the helicopter is approximately 262.5 km/h.

Answer

The speed of the helicopter is approximately 262.5 km/h.
