Question

Два самолёта летели с одинаковой скоростью.Один самолёт был в полёте 4 ч,другой -6 ч.Первый самолёт пролетел на 1400 км меньше второго самолёта.Сколько километров пролетел каждый самолёт?

Answer 1

1)6-4=на 2(ч)2 самолёт пролетел больше чем первый;
2ч=1400км
2)1400:2=700(км)за 1 час;
3)700*4=2800(км)пролетел 1 самолёт;
4)700*6=4200(км)пролетел 2 самолёт.
Ответ:2800км и 4200км.

Answer 2

1)6-4=на 2 часа больше-был в пути второй.
2)1400:2=700км/час-их скорость.


3)4*700=2800км-пролетел первый за 4 часа.


4)6*700=4200км-пролетел второй за 6 часов.0/0 Нравится Пожаловаться

Answer 3

Calculating the Distance Traveled by Each Plane

Two planes flew at the same speed, with one in the air for 4 hours and the other for 6 hours. The first plane flew 1400 km less than the second plane.

To calculate the distance traveled by each plane, we can use the formula: distance = speed * time.

Let's denote the speed of each plane as "s" and the distance traveled by the first plane as "d1" and the second plane as "d2".

We can set up the following equations based on the given information: 1. For the first plane: d1 = 4s 2. For the second plane: d2 = 6s 3. The first plane flew 1400 km less than the second plane: d2 - d1 = 1400

We can solve these equations to find the distance traveled by each plane.

Calculations

Using the equations above, we can solve for the distance traveled by each plane:

From equation 1: d1 = 4s From equation 2: d2 = 6s From equation 3: d2 - d1 = 1400

Substitute the expressions for d1 and d2 from equations 1 and 2 into equation 3: 6s - 4s = 1400 2s = 1400 s = 700

Now that we have found the speed (s), we can calculate the distance traveled by each plane: - The first plane traveled: 4 hours * 700 km/h = 2800 km - The second plane traveled: 6 hours * 700 km/h = 4200 km

Therefore, the first plane traveled 2800 km, and the second plane traveled 4200 km.
