Question

Скорость вертолёта 240 км/ч. Это в 8 раз больше скорости теплохода и в 4 раза меньше скорости самолёта. Найди скорость теплохода; скорость самолёта. УСЛОВИЕ И РЕШЕНИЕ

Answer 1

Ск. вертолета- 240 км/ч
ск. теплохода- в 8 раза меньше
ск. самолета- в 4 раза больше

1) 240:8=30 км/ч скорость теплохода
2) 240*4=960 км/ч скорость самолета
Ответ: скорость теплохода - 30 км/ч, скорость самолета- 960 км/ч.

Answer 2

Problem Analysis

We are given that the speed of a helicopter is 240 km/h, which is 8 times faster than the speed of a ship, and 4 times slower than the speed of an airplane. We need to find the speed of the ship and the speed of the airplane.

Solution

Let's assume the speed of the ship is x km/h and the speed of the airplane is y km/h.

According to the given information: - The speed of the helicopter is 240 km/h. - The speed of the helicopter is 8 times faster than the speed of the ship, so we can write the equation: 240 = 8x. - The speed of the helicopter is 4 times slower than the speed of the airplane, so we can write the equation: 240 = y/4.

To find the speed of the ship, we can solve the equation 240 = 8x for x: 240 = 8x x = 240/8 x = 30

Therefore, the speed of the ship is 30 km/h.

To find the speed of the airplane, we can solve the equation 240 = y/4 for y: 240 = y/4 y = 240 * 4 y = 960

Therefore, the speed of the airplane is 960 km/h.

Answer

The speed of the ship is 30 km/h and the speed of the airplane is 960 km/h.
