Question

Самолет пролетел s км за 2 часа а вертолет пролетел это же расстояние за 3 ч. На сколько скорость самолёта больше скорости вертолета?

Answer 1

( s / 2 ) - ( s / 3 ) = ( 3s - 2s ) / 6 = s / 6 = 1/6s ( км/час ) ; Ответ на 1/6s км/час больше

Answer 2

Calculation of Speed

To determine the difference in speed between the airplane and the helicopter, we need to calculate their respective speeds. We are given that the airplane traveled a certain distance in 2 hours, while the helicopter traveled the same distance in 3 hours.

Let's assume the distance traveled by both the airplane and the helicopter is s kilometers.

The speed of an object can be calculated by dividing the distance traveled by the time taken. Therefore, the speed of the airplane can be calculated as s kilometers / 2 hours, and the speed of the helicopter can be calculated as s kilometers / 3 hours.

Speed Comparison

To find the difference in speed between the airplane and the helicopter, we need to subtract the speed of the helicopter from the speed of the airplane.

Let's denote the speed of the airplane as v_airplane and the speed of the helicopter as v_helicopter.

The difference in speed can be calculated as:

Difference in speed = v_airplane - v_helicopter

Substituting the values we calculated earlier, we have:

Difference in speed = (s kilometers / 2 hours) - (s kilometers / 3 hours)

Simplifying the equation, we can find the common denominator and subtract the fractions:

Difference in speed = (3s - 2s) kilometers / (2 * 3) hours

Difference in speed = s kilometers / 6 hours

Therefore, the difference in speed between the airplane and the helicopter is s kilometers / 6 hours.

Conclusion

Based on the given information, the speed of the airplane is greater than the speed of the helicopter by s kilometers / 6 hours.

Please note that the specific value of the distance traveled (s kilometers) was not provided in the question, so we cannot determine the exact numerical difference in speed.
