Question

с одного аэродрома одновременно в противоположных направлениях вылетели самолёт и вертолет. скорость самолета 740 км/ч а скорость вертолёта 260 км/ч .какое расстояние будет между ними через t часов после вылета? запиши ответ в виде формулы и упрости её. что означает число 1000в получившийся формуле?

Answer 1

Problem Analysis

We are given that an airplane and a helicopter take off from the same airport simultaneously in opposite directions. The airplane has a speed of 740 km/h, and the helicopter has a speed of 260 km/h. We need to find the distance between them after t hours.

Solution

To find the distance between the airplane and the helicopter after t hours, we can use the formula:

Distance = (Speed of the airplane + Speed of the helicopter) * t

Let's substitute the given values into the formula:

Distance = (740 km/h + 260 km/h) * t

Simplifying the formula:

Distance = 1000 km/h * t

The number 1000 in the formula represents the combined speed of the airplane and the helicopter.

Therefore, the simplified formula for the distance between the airplane and the helicopter after t hours is:

Distance = 1000t

Example Calculation

Let's say t = 2 hours. We can substitute this value into the formula to find the distance:

Distance = 1000 km/h * 2 hours = 2000 km

So, after 2 hours, the distance between the airplane and the helicopter will be 2000 km.

Conclusion

The formula for the distance between the airplane and the helicopter after t hours is Distance = 1000t, where t is the time in hours. The number 1000 in the formula represents the combined speed of the airplane and the helicopter.
