Question

3) Два вертолёта одновременно вылетели навстречу друг другу. Ско- рость одного вертолёта 257 км/ч. Он до места встречи пролетел 1 285 км. Какое расстояние пролетели вертолёты, если скорость вто- рого вертолёта равна 226 км/ч?​

Answer 1

Ответ:

Найдём время полёта вертолётов:

1285÷257 = 5 ч

226 · 5 = 1130 км - расстояние второго вертолёта

1285+1130 = 2415 км - пролетели вертолёты.

Ответ: 2415 км.

Answer 2

Problem Statement

Два вертолёта одновременно вылетели навстречу друг другу. Скорость одного вертолёта составляет 257 км/ч, и он до места встречи пролетел 1,285 км. Какое расстояние пролетели вертолёты, если скорость второго вертолёта равна 226 км/ч?

Solution

To find the total distance traveled by the helicopters, we can use the formula:

Total distance = Distance traveled by Helicopter 1 + Distance traveled by Helicopter 2

Given that the speed of Helicopter 1 is 257 km/h and it traveled a distance of 1,285 km, we can calculate the time it took for Helicopter 1 to reach the meeting point using the formula:

Time = Distance / Speed

Substituting the values, we get:

Time taken by Helicopter 1 = 1,285 km / 257 km/h

Now, since both helicopters started at the same time and are traveling towards each other, the time taken by Helicopter 2 to reach the meeting point would be the same as the time taken by Helicopter 1.

Using the time taken by Helicopter 1, we can calculate the distance traveled by Helicopter 2 using the formula:

Distance traveled by Helicopter 2 = Speed of Helicopter 2 * Time taken by Helicopter 1

Substituting the values, we get:

Distance traveled by Helicopter 2 = 226 km/h * (1,285 km / 257 km/h)

Now, we can calculate the total distance traveled by adding the distances traveled by both helicopters:

Total distance = Distance traveled by Helicopter 1 + Distance traveled by Helicopter 2

Substituting the values, we get:

Total distance = 1,285 km + (226 km/h * (1,285 km / 257 km/h))

Calculating this expression will give us the total distance traveled by the helicopters.

Let's calculate it:

Total distance = 1,285 km + (226 km/h * (1,285 km / 257 km/h))

Total distance = 1,285 km + (226 km/h * 5 km)

Total distance = 1,285 km + 1,130 km

Total distance = 2,415 km

Therefore, the helicopters traveled a total distance of 2,415 km.
