Answer 1

1) 3*240=720 (км)
2) 720\12=60 (км\ч)
Ответ: 60 км\ч скорость поезда

Answer 2

Problem Statement

A helicopter travels a certain distance in 3 hours at a speed of 240 km/h. We need to find the speed of a train that can cover the same distance in 12 hours.

Solution

Let's denote the speed of the train as x km/h.

The distance covered by the helicopter is given by the formula: distance = speed × time

For the helicopter: distance = 240 km/h × 3 h

For the train: distance = x km/h × 12 h

Setting the two distances equal to each other, we can solve for the speed of the train:

240 km/h × 3 h = x km/h × 12 h

Solving for x: x = (240 km/h × 3 h) / 12 h

Now, let's calculate the speed of the train: x = (240 km/h × 3 h) / 12 h

x = 720 km / 12 h

x = 60 km/h

Answer

The speed of the train is 60 km/h.
