Question

∉реактивный самолёт за 3 часа пролетел 2580 км а вертолёт 430 км во сколько скорость вертолёта больше скорость вертолёта?

Answer 1

2580:430=6 (раз)
Ответ: скорость самолета в 6 раз больше скорости вертолета


Можно длинным путем:
2580:3=860 (км/ч) скорость самолета
430:3=143 1/3 (км/ч) скорость вертолета
860:143 1/3=6 (раз)
Ответ: в 6 раз

Answer 2

Calculating the Speed Difference Between the Jet and the Helicopter

To find out how much faster the helicopter is compared to the jet, we can calculate the speed of each vehicle.

Given: - Distance traveled by the jet in 3 hours: 2580 km - Distance traveled by the helicopter in 3 hours: 430 km

Calculating the Speed of the Jet

To calculate the speed of the jet, we can use the formula: \[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

Using the given distance and time: \[ \text{Speed of the jet} = \frac{2580 \text{ km}}{3 \text{ hours}} \]

\[ \text{Speed of the jet} = 860 \text{ km/h} \]

Calculating the Speed of the Helicopter

Similarly, to calculate the speed of the helicopter: \[ \text{Speed of the helicopter} = \frac{430 \text{ km}}{3 \text{ hours}} \]

\[ \text{Speed of the helicopter} = 143.33 \text{ km/h} \]

Comparing the Speeds

Now, let's compare the speeds of the jet and the helicopter.

The speed of the jet is 860 km/h and the speed of the helicopter is 143.33 km/h.

Conclusion

The speed of the helicopter is 716.67 km/h less than the speed of the jet.
