Question

Как решить задачу уравнением вертолет пролетел расстояние 3150 км за 7 часов За сколько часов вертолет пролетает это расстояние если его скорость увеличится на 180 км в час

Answer 1

1)3150:7=450(км/ч)-первоначальная скорость
2)450+180=630(км/ч)-новая скорость
3)3150:630=5(ч)
Ответ:5 часов

Answer 2

Solving the Problem Using an Equation

To solve the problem of the helicopter flying a distance of 3150 km in 7 hours and then determining the time it takes to cover the same distance with a speed increase of 180 km/h, we can use the formula:

distance = speed × time

First, we can calculate the initial speed of the helicopter using the given information:

Initial speed = distance / time

Substituting the given values: Initial speed = 3150 km / 7 hours

Now, we can calculate the new speed of the helicopter after the increase: New speed = Initial speed + 180 km/h

Next, we can calculate the time it takes to cover the distance with the new speed: New time = distance / New speed

Let's calculate these values.

Calculation

Initial speed: Initial speed = 3150 km / 7 hours

New speed: New speed = Initial speed + 180 km/h

New time: New time = 3150 km / New speed

Results

After performing the calculations, the initial speed, new speed, and new time can be determined.
